I'm trying to integrate Oculus leaderboard into my Unity game for Gear VR, but when I call Oculus functions like GetUserProof(), Leaderboards.GetEntries() or Entitlements.IsUserEntitledToApplication() callbacks are never called. I noticed that CallbackRunner.cs script which contains Request.RunCallbacks() was not set to any object, but even after I set it to an empty game object nothing happened.
Has anybody had the same problem before? Is it a problem with the sdk or am I doing something wrong?
Thanks in advance.
