I know others have reported various versions of the disconnect bug already, but i wanted to give the developers the details I have. Ipad air 2, 64 GB, running ioS 9.2.1. For the past five days, once per day i experience what appears to be a disconnect. It only happens after a battle has finished or immediately after loading into a battle. When it happens after a battle is finished, the game sits at the "Battle is Finished" screen until I realize I need to disconnect - no big deal in this instance. When it happens just after loading into battle, it is a serious issue as it takes at least two minutes to get back into game.
(1) When it occurs just after loading into battle it is immediately apparent:
(2) If I close the app and try to relaunch it, it will start to load in and just stick at the "Connecting" tab while never actually doing so. The login credentials part does not appear as it tries to use the previously supplied credentials.
(3) In order to fix the problem, I have to reset the ipad completely. It then states that the "Autologin session has expired." If I re-enter the password, it will then connect to the game.
I don't know if this is helpful to the developers in fixing the disconnect issue that a bunch of people seem to be having. It is very frustrating to have a bad game at least once a day due to this issue.
