Game Center, Multiplayer, Sandbox

I’m trying to implement turn based multiplayer via Game center. I have two iOS devices signed in to game center in Sandbox mode. I’m getting strange results - sometimes turnListener gets turnData, but some times not. When I open matches in Game Center turns are always there.

 Sandbox mode or my code is not good? Sandbox always reliable?

Are you trying to achieve asynchronous turn-based game play or real-time turn based?

For real-time… here is a great tutorial using AppWarp

For asynchronous… here is one that use App42 backend
