Multiple Arfoundation scenes

Hi, I have a problem with switching between multiple scenes that all have ARsessions. When I first load any scene it works fine but then I'll switch back to the main menu and then reload the same scene and it's just black. Or if I switch to to another scene the camera tracking doesn't seem to work. What is the proper way to end an ARsession and be able to start another session. Still using arfoundation 2 , but I seemed to have the same problem in version 3.

 

Did you found the solution ? I've got a probleme when switching from one AR Scene to another. The first loaded ARScene works well, the second seems to have Origins problems, my prefab don't appear at the right place, if I switch the 2 scenes, it's always the second one causing problem. I can't figure out how to reset if correctly.
