With PolySpatial 1.1.4 + Unity 2022.3.19f1 (and 20f1), there are two scenes in my game; initial scene is bounded volume, and other one is unbounded mixed reality scene. On application start, GameCenter shows signed in notification as expected, but whenever I load unbounded scene or vice-versa, the notification appears again. It does not exist such a problem in PolySpatial 1.0.3 (both Unity .19f and 20f1).
