GooglePlayGames loses connection when changing scenes

Unity Engine
1

Hi people. Me and my team are working in a college VR project, we’re pretty new in unity. We’re using GooglePlayGamesServices for the real-time multiplayer sync. We have a menu scene where we stablish connection between the players (only 2 for now), using CreateQuickGame(). If we try to broadcast a message, it works, as long as we stay in that scene. As soon as we change the scene, we get this log:

And any message we try to send from the other scene won’t be received by anyone.

The script that executes the message functions is called MultiplayerManager. It extends from RealTimeMultiplayerListener, and it seems to be persisting through scenes because we don’t get a null pointer exception when we do MultiplayerManager.Instance.SendMessage(“Message”). However, any connection seems to be lost when changing scenes. Do I need to do something else to keep the connection across different scenes? Thanks in advance.

Bump.

I just noticed something weird. What’s breaking the connection is not the scene change, but the switch to VR mode. I ran some tests and the game works fine as long as I stay in or out of VR for the entire session. As soon as I do this:

IEnumerator LoadDevice(string newDevice)
        {
            VRSettings.LoadDeviceByName(newDevice);
            yield return null;
            VRSettings.enabled = true;
        }

The connection is lost. Even loading the device before and enabling VR after the connection breaks it. The only way to avoid this is to reconnect after enabling VR mode, but that won’t work for quick matches (as GooglePlayServices doesn’t let you reconnect to the same player). Is there any way to avoid losing the connection when switching to VR?
