Photon Network - Game version conflict

Hey everyone, how to properly seperate users with other game version on Android?

My problem is that I updated my app to a new version, however the older users who not updated the game to the newest version are get in the same multiplayer room where the newest version players are in.

This causing huge glitches since I did some enviromental changes in the app.

So the question, how to make sure older version players not get in the same multiplayer room where newest version players are in?

Thanks in advance.
