Looks like a patch was released about two hours ago. Ever since then, after I complete a match, the game “loads” indefinitely. I have to close out of the app and reopen and it works fine again…for one match.
iOS 7.1, iPhone 5.
A new patch was just released and I am not experiencing the issue anymore - thanks!
My game is still loading. The whole day already. Open/close app doesn’t help.
iPhone 5S, iOS 7.1
It’s ok now. Don’t know how, but it was fixed…
I still have this issue 
Backup and reinstall finally solved it for me.
