Quest 2 app execution error

I'm testing the Quest 2 app, and when I run the app, the entire screen of the app follows the quest movement.

When wearing a quest, the screen should be visible according to the movement within the app, but the entire app screen moves.

In other words, i only see the fixed screen, and the fixed screen continues to follow me, and i cannot change my view to see the entire screen.

How to solve this phenomenon?
