Rating it 1 star until they fix the mobile notifications that have been broken since like May or June.. (talking about the notifications that pop, and when you click on them, slack opens to the channel.. without the new messages being displayed - you need to force-close the app and reopen it for it to refresh). Makes it utterly painful to use on mobile.

I am writing this in hopes that someone from the developing team views this message about a suggested change I have in regards to using the mobile app. When viewing messages inside a channel on the mobile app, if a member is currently typing, Slack will notify you with a recurring message at the bottom of the chat stating "${member-name} is typing...". This notification message is recurring until the member finishes typing. The problem with this feature in the mobile app is every time this notification message recurs it shifts all messages in the channel up slightly to make room for the notification message to be displayed. When the notification message temporarily disappears it shifts all messages back down. The continual shifting up and down anytime another member is typing makes reading the other messages in the channel very difficult and unpleasant. This is a great app, I use it for both work and personal use. Thank you to all the developers that have made the overall experience so good. I hope this review reaches the right team(s) and this isolated yet impactful issue is resolved.

Unfortunately terrible app for larger screens. I've already discussed the issue with support, but there is no progress at all. There is much better app for iPad, but Android tablets or ChromeOS devices has matured in last years too. With beasts like Samsung S8+ like I have it's pretty much unusable. And due to deep links it is not possible to sign in into web version. It is sad experience nowdays.

The Android app is decent but pales in comparison to the desktop application. The app sometimes enters a state where it is impossible to change workspaces without restarting the app. And also sometimes will not recognize what a message has already been read, leaving you with a notification badge that you cannot get rid of of.

The app works well...but there are issues on z fold 3 with text overlaying over each other. Pressing DMs and then the add button will show a screen with the new message overlaying the input section "type a name or person into the chat" Since this is a frequently used feature I think its important to fix asap. 2/5 stars until fixed.

It just never properly syncs my conversations when I'm away from my desktop. I'll check my phone and like half of the conversation will be missing from my phone. On my phone I'll also get new notification dots with someone and when I open it it's still the old conversation and so the notification dot never goes away because it won't load the new message. Such a flop in comparison to discord. Wouldn't use it at all if my work didn't use it.

Update for 3-30-22 Was actually going to rate the app higher than my original review as September 2021 through January 2022 were mostly without incident and the app functioned as intended. The last 2 weeks however have completely removed that built up goodwill. Right back to it's old ways of deleting photos in the cache, kicking you out of keyboard and speak to text UI's, and consuming battery too quickly. I hate it. It has been detrimental to my work.

Please fix frame rate issue bugs with 90-120hz on phones (using Pixel 6 Pro) it is very Janky and it stutters it makes the app terrible to use. So much so I don't want to use the app please push out an update to fix this! It used to work fine a few months ago but now it is inconsistent and stutters when you scroll through chats. Please can you fix this with an update. It is crucial to use for work!

My experience so far on the app has been less than pleasant. Whenever I join or start any huddle from my android phone, it closes after about 15-20 seconds. This is affecting my project. I've updated the app and also tested my network. The network speed is optimal. Despite doing this, I still experience the same issue

Sometimes shows Unread Notification when there are no unread messages. May take few seconds for new messages to arrive only on Phone app. Huddle feature across machine to phone is slightly buggy but yeah I guess it will get there..Otherwise a good app overall. Again it has started to take considerable time to load the message when clicked on notification.

The mobile app crashes constantly. The panel at the bottom does not appear almost every time I open the app. In occasions when the app shows everything properly, it freezes after a few minute, even in the middle of message composing.

Rac. P. May 15, 2022     

Shows badge icon when there aren't any messages. This makes it useless, as you can't tell when you actually have any messages. Regarding your response: I'm afraid "have you tried turning it off and on again" is kinda patronising, not very helpful, and betrays quite a high level of ignorance on your part

Can't use send now when scheduled messages. The attachment upload is annoying revert it back. Often videos can't play. Sometimes messages are stuck and can't deliver them. Just please don't do anything on this app, it was working perfectly... now with every new update it's more broken.

Cha. V. v. May 15, 2022     

When a message is typed, send button is not working. I have to press back button to close the keyboard, reopen the keyboard, and then send the message. Also, the cursor cannot be pointed at somewhere we need. To do that also, I have to follow the same above procedure.

Amb. H. May 18, 2022     

After the latest update, I can open the app but I cannot scroll or click on any channels. It's not responding at all! My phone itself has no issues, it must be Slack. I've cleared my cache and everything but no help there.

Fairly frustrating Mobile app. When there are new messages, the channel jumps to the top by design, sometimes it doesn't make that jump and simply disappears. Huddles and calls are often missed if I don't accept on the first half of the first ring. Desktop slack is a fantastic collab tool. App slack is frustrating at best.

The huddle and call via my bluetooth headset were working fine till the last update. Now the bluetooth microphone doesn't work. After about 15 seconds the huddle drops with a message that there is a problem and that I can try again later. The huddle and call work fine without the bluetooth headset. The calls via the same headset work fine on other apps. Tried everything, like clearing cache/data, force stop, re-granting permissions, uninstall/reinstall and finally restarted, the problem remains.

It's still giving me an "unable to update notification settings" error after I gave the app unrestricted battery usage. I did the troubleshooting but it can't seem to find the error. I've double checked all the settings I can find, maybe there's some kind of incompatibility going on?

1. It's hard to log in with authenticator app. When I click on the email link, I can't minimize the app to look at the code in authenticator. Otherwise, it throws me back to signin page 2. Need a refresh button - The reason I got into this mess is because the latest data wasn't getting loaded, even after clearing cache. So I had to clear data.

Overall, I like Slack (beats tf out of MS Teams, but that's an impossibly low bar), but the notification system is completely unreliable by default and extremely obtuse to configure. I've combed through every notification setting I can find, and it still fails almost more often than not. Because of this, Slack straight up does not work for a family chat.

I always have problems with this app posting pictures, and it runs very slowly. It constantly changes screens when I try to type in a group chat, and the picture will never load or upload, and when I click on a photo, it shows me something else. This app is very broken.

Ada. K. May 23, 2022     

Unusable after last update, the button to send a message doesn't work Edit: That's an amazing response time :) I sent you an email with a video to illustrate the problem.

J. C. May 23, 2022     

It's been working fine for me when I had an s10. I upgraded to an s22 ultra and now it disconnects calls after 30 seconds when I use a Bluetooth device. Without a Bluetooth it works fine and the Bluetooth works fine when I use it on phone calls or discord

Notifications have been turned on in preferences but the app consistently misses DM and new post notifications. Only made aware of posts and messages when I sign into desktop Slack program. Android platform may be to blame but I am disappointed in this app's performance.

Dav. H. Apr 30, 2022     

I really like this app and use it daily, EXCEPT recently I tried uploading eleven pictures at once (my mistake maybe) but now it's stuck with a constant can't upload error message. I have a solid internet connection so it's not that. It keeps saying retry, which I do, but continues to fail. How do I clear this annoying upload error message?

Kat. R. Apr 30, 2022     

It removed me from my employer's channel and said that my free trial was over. It says I have to pay for it. Then it takes me to plans but there's a free option. I can't click on it or anything at all. Not a single other person in the company that I work with is paying for this, and they've been using it for months if not a year. I'm literally missing vital work info because of this, and I can't get anywhere. I'm literally just sent in circles with nothing resolved, no answers on how to fix it.

Tom. B. May 3, 2022     

For whatever reason I'm having a lot of trouble with the keyboard just disappearing mid type, lot of trouble with the voice dictation as well. Just randomly shuts off while I'm dictating.

The app is find and all, but it seems to be lacking one of the most basic functions. I have two separate emails I use to access my slack depending on my work. Would be more helpful to have a log out option or account switch option. I literally have to uninstall then reinstall the app to 'log in' with my other email.
