Third Party PUN2 second start game problem

Hi,
When I scene start to connect with the Master server after than when I press the button it joins to room or creates new, but find the opponent! Then change the scene and start the match.
When the player leaves the game, I can find the opponent again but when starting the match in the next scene everything is freeze (like pause).
I'm using android device.
Why??
