its working fine now so I have changed my rating thank you so much for your efforts. Hi Team, I am using calsign app from 6 months but from today onwards the app is closing automatically even though I have done reinstallation but no luck, its closing as soon as I have opened it. Can you please help me to sort out the issue.

Totally agree latest version of this app is absolutely rubbish. It worked for a few hours one day and now can't access it. It keeps crashing. I hope it gets sorted ASAP as this affects my daily role.

Poor app. Stopped working with automatic sync some time ago meaning my only option is to constantly use the manual passcode option. Tried upgrading and reinstalling but to no avail.

The latest version of this app is rubbish. Even unable to open the app to register/login. The older version was stable and worked very well for almost 2 years.

Unstable, extremely slow...in all a useless application. 9 out of 10 times, you wont get a punsh notification on your phone. You have to open the app and refresh to get the incoming request. For the past few days, even opening the app says check internet connection. I dont understand how big enterprises can deploy such a pathetic app in to their eco system. Have you guys tested your app? Edit: I can conclude that this is the worst app I have ever used in my life...it sucks and big time

Unable re-active the account in android after signed off. It is asking last 3 digits of the phone number. After entering the first digit, all gone blank and no response. Seems this app only works with iPhone. Either I should change my phone or job.

Forced to use this by my company only to have it crashing on splash screen. Outstanding job guys! It is about as stable as lunatic with a semi automatic.

Most of time doesn't work with incoming request. Always show some error or keep loading for a very long time.

Kam. R. May 14, 2021     

Can't open the app, causing me to sit Idle as I can not complete my daily work/anything. Not sure if this is the app worth approved by my organization. Tried restarting mobile and reinstalling multiple times, but no luck.

Useless and worst performance Tried registering more than 20 times, but no success. No sms and call. Still waiting to register. I am surprised why companies are choosing this app.

Sum. J. May 18, 2021     

It doesn't even allow registering new callsign let alone using it. Keep throwing error 'Something went wrong. please try again later' on screen when it should send verification SMS.

Useless app with no support. The app is broken on android for days blocking access to my organisation's resources for days. Had to get an iPhone to use it. No support whatsoever. Worthless devs who have no clue of what they pushed in the latest update.

App keeps crashing while launching. Can this issue be fixed at the earliest? Uninstalled and re installed but still no luck.
