Hi everybody! I'm working on a very simple MARS app. There are 3 scenes: 1 - A simple menu to choose one of the other 2 scenes 2 - An AR scene with one ImageMarker that triggers the display of some prefabs 3 - An AR scene with face tracking, to show some prefab around the face of the user The app works well on Android phones but on iOS only the first executed AR scene works well. If I return to the menu and choose the other scene (or the same scene) it doesn't work anymore. In other words consider the following sequence: - Execute the app - In the menu choose scene 2 or scene 3, it works well - Return to the menu (there's a button for this action) - Choose scene 2 or scene 3, it doesn't work. Any suggestion ? Thank you in advance.
