My turn based app "seekingFriends" failed working since the new version of Game Center. Here is the scenario: Player A originate the game and invited player B. Player B gets the invitation and the  func player(_ player: GKPlayer, receivedTurnEventFor match: GKTurnBasedMatch, didBecomeActive: Bool)  was triggered. However, when player B tried to get the match data via function call loadMatchData, it got nothing. No error happened as well.

Why my game center app (SeekingFriends) was in "In Review" status for over a month?
