Hi guys, So far Game Center has been adequate to what I expected, after I downloaded it today. My only niggle with it is that when I was inviting a friend to a friendly game of Fruit Ninja, the invite would just keep on running and no push notification asking for a decision regarding whether or not to accept or decline would come up on the other person's screen, meaning that we could only play with some randoms on the interwebs. I have checked that push notifications are on on both devices and nothing has happened in the actual Game Center app. So... any ideas or solutions? Thanks in advance guys.
