I'm developing a real-time multiplayer game for Android an iOS with Google Play Game Services. I'm using the C++ API of it, with Cocos2d-x.
The GPG is implemented in the game as Google's documentation tells and this works well on Android. But on iOS, the game crashes after the real-time room has enough players.
Snapshots are not enabled and I'm using Google's UI for real-time room.
Other functionality works well, the tested ones:
Invitations from friends
Invitating friends
Leaderborads
Showing Achievements UI

Have you tried this by using real iOs device? This error occurs in iphone simulator for me.
