Question Define "Move device slowly. Wait for tracking to begin." Where's the error?

Needed to do a few AR projects and got some working, however when I want to do one that looks for objects that are similar to the ones referenced in its library, the app doesn't work.

I launch my android app and instead of it going to the main screen that it should, I have a black screen with text saying "Move device slowly. Wait for tracking to begin." What does this mean? Where have I gone wrong? Why do I get some sceen that has not been mentioned in my editor?

What if the app needs to request access to the camera? I open the security settings and I don't get given a choice of allowing the app to use the camera.

Anyone know a fix to this? Don't have anyone to go and make sure this issue is consitant across multiple devices, that just my phone isn't bugging out.
