Why my apk won’t start in full vr mode? Although (Start in VR) is checked ☑️

I’m using (4.27.2) after I packaged my game as android and import it to quest 2, and open it, it doesn’t go FULL VR mode, what am I missing? Please help as I tried many things to no avail : (

BTW this is Collab Viewer.

A video below to explain my issue, it’s only 10 seconds long.

P.S: (Start in VR) is checked

Have you added the oculus quest on Android → Advanced APK Packaging → Package for oculus mobile devices? Add quest and quest 2
This solved the problem to me.
