I recently build my game for android, I am facing issue while loading between scenes, The Photon's LoadLevel() method is not working on android phone, Normal Load Scene callback by unity does load scenes but the Photon's Method Doesn't
PUN is using the "normal" Unity scene loading.
Update PUN 2, if you didn't in a while. Make sure to use an LTS version of Unity.
Provide some more insight / error logs.
