Cc not login, last 5 hours. I am trying lot.
My two devices are same problem
May I suggest that you clear the cache for the app and check your wifi connection. If this does not resolve the issue you may need to uninstall and reinstall CC. Good Luck!
Also check internet connection, cause maybe your internet provider have problem with connection. Does bottom bas is loading, or you are receiving "Connection loginserver failed" without even seeing game data loading in "%" value on that screen ? If your internet connection is poor, game will not load and you will not see any loading progress.
Reinstalling game should fix apk related problems. If those will still happen, than try to contact live support with information about your devices, so they can check if those are supported (and i haven't heard any device is not supporting CC)
