How to synchronize the application when the player enter after some changes in the scene??

I am using photon pun 2 in a multiplayer scene. When players enter the scene at the same time, all animations and objects remain synchronized, but if the player enters after some changes, they will see the scene as it was at the beginning, different from the others players that was already in the room.

Objects that need synchronization have photon view and photon animator view on them.

How can I resolve this problem?
