In iOS 10, Game Center invitations are handled differently than in prior iOS versions (they are sent via the Messages app instead of the Game Center app w/ push notifications). It appears that this is causing issues with the “participants” portion of Game Center turn-based match data (specifically, before the match starts). Corona team: Is this a known issue that is being worked on? According to this: https://developer.apple.com/library/content/releasenotes/General/WhatsNewIniOS/Articles/iOS10.html and this: https://developer.apple.com/reference/gamekit/gkgamesession, it seems like you may need to modify the Game Center plugin to include GKGameSession data for devices running iOS 10.
Also, Game Center is not passing turns back and forth correctly in iOS 10 (for turn-based games). Is it possible that this is also related to the new GKGameSession class?
I appreciate your help!
