game center not connect
i cant invite my game center friend for multiplay games suddenly.
my wife and i usually play some multiplay games ( like gun bros, finger soccer...) by inviting each other throught game center. it went well until this Tuesday, we suddenly cant invite each other anymore. the game center shows status of "waiting" forever after sending invitation. Sometime the device shows notification from game center. we can accept the invitation and go into the game, but the game keeping loading and still cant connect to each other.
i am sure we dont change any game center settings.
