So, until today I'd been unaffected by login issues. But now I can't get past the splash screen on either wifi or data. What's happening with the other login issues, is it the same or different?
Since the last software download you cannot get past the login screen if you don't have a functioning connection to OTM servers.
If you are having problems at a server reset or boss call the problem is just likely to reoccur.
If you have internet connectivity, such as safari (for iOS), then the issue appears to be a handshaking bug when connecting.
What fixes it on many devices is to:
1) use a vpn. There are apps for this on iOS and android.
2) force close ch, try another connection type (different wifi, or switch to from cellular), launch CH
3) force close CH, close your connection (example:
Turn off wifi or cellular data), open CH, wait on the splash screen for about 30 seconds, force close CH, open/enable your connection, open CH again and log normally.
I haven't tested 2,3 on android devices but I have heard option 1 does work. There will hopefully be a fix soon.
