Black screen

Also i noticed some animations glitches.

these pixel glitches or what they call them, are only present on my samsung a55.  the other samsung model don't have them.

If I'm not misunderstanding, I have this black screen bug too on Android, and it's different than the black screen bug from a month ago. 

So, this happens only on mobile for me, and only started happening since Polandxit, although it might have been since the last update. 

How to reproduce this bug: 

1. Open the android app and login

2. Close the app (the session will not logout, which is normal on mobile)

3. Open the app again, you get a black screen, you are still logged in, but the app won't load anything, even while you have active tables

4. Go to the website, to settings, multiple authentications, and kill the mobile auth session. 

5. The black screen app will immediately react and you will get the log in again page (clicking log in again will open a full unibet page in the app which is also a separate bug)

6. Close the app and reopen, you can now log in.

This happens every time, starting a different session on a different mobile or PC does not solve the issue, just killing the session, or waiting 2 hours for it to expire.

If you log out instead of just closing the app it works fine.

If you select a country different than your own on the login screen, you will not get a black screen, but you will be prompted to login again, as was the case until now as well. Likely not intended behavior but normal behavior. (this produces numerous auth sessions that you can only close from the browser)

If you select a different country log in, close, reopen, you will get a login screen. If you then select your local country then the screen will go black.

It's pretty clear that it trying to revive an active session fails somehow 

Later edit: 

Interestingly enough, this does not happen on my Android 8 device, but even if I don't have an active session and start one on Android 8, it will result in a black screen on my Android 12 device, so any mobile auth session can brick it if a proper logout has not been done on the device.

I managed to replicate both bugs with the steps provided by @FeelsBadMan.

Black screen + full unibet page in the app after trying to log in again.

Android 12, android studio.

What happens is that I don't know how many times, I can't open the application, after I turn off the phone, black screen, I have to uninstall and then reinstall it to work.
