Position of 3D object on host are not sync with the client in Collaborative AR

Hello, I am currently doing a project about multi-user interaction in collaborative augmented reality interface with multiple markers. I used vuforia, photon unity networking and unity version 2022.3.12f1. To display the object A, two markers need to collide with each other. However, my problem is the object A are not sync for host and clients. Host can view the object A on the right position (on the marker) while clients cannot see the object. The object go far from the marker (if I see from the scene view).

I’ve tried to put Photon Transform View on the object. The object are on the right position but it shaking all the time so the collaborative part cannot be seen clearly. Can someone help me to fix this?

This is the code to display the object (collide two markers)

This sounds like a networking question, not an XR question. I think you’ll get better responses if you post in the Photon forums.
