Has anyone else experienced this issue? I'm running into an issue in development and have only tested on iOS so far. Vuforia v. 8.6.7 Unity v. 2019.2.11f1 I have a scene that uses a Plane Finder to detect and initiate a Ground Plane Stage. When I initialize the Ground Plane in the app and then navigate to a different app, when I come back to my app, the Ground Plane and all child elements are gone. The log shows that Vuforia Positional Device Tracker is stopping and starting as the app goes in the background and comes back to focus. I can reinitialize the ground plane using the finder but I’d rather not have to do that if possible. Is there a way to maintain the placed ground plane even when the app is out of focus and running in the background?
