Step by Step:
Iam in the "team" screen, editing my team. Then i go to home screen to view my opponent, clicking on the "game preview" button -> then a spinner shows up "reconnecting" and i get the Intro Screen of Top11.
After this it get stuck with the message i mentioned above. So i have to close the app (square icon, close app by swiping it "away") and restart it by opening app again.
This also happens during a game, not always but sometimes, most when i just watch the game, then after 3-5 minutes i go to the tactic screen, edit my tactics or bring in some subs, then it reconnects.
Mostly, until i finished the procedure from above, the game is over....
