Hooray, new update etc. I haven't installed anything since iOS 8 as I like my games and Gamecenter to work. I am really tired of some new games not working and want to upgrade, so my question is in the headline really. Did iOS 9.3 fix anything for gamers?
When I was beta testing iOS 9.3 beta 1 the game centre bug popped up again. When the next beta arrived I updated and it worked again. I don't know if this is a complete fix but I logged out of gamecenter and logged back in with my iCloud.com email and haven't had any problems since.
