In Android 13 on a Pixel 6 device, Minecraft refuses to scale, go fullscreen (there is a black bar where the front facing camera sites), and as a result the entire screen is pushed to the right. However, while the buttons are visually pushed to the right, the button detection remains where they should be if it was fullscreen/scaled. As a result, you have to press considerably to the left of the screen buttons - especially inventory, pause, and other center-display buttons - to do anything.

This is visible on the main screen and during gameplay - see attached screenshot and note how the version is cutoff and pushed right.

UPDATE:  By locking the phone while the app is open, then unlocking the phone, the app will then scale properly and buttons will place correctly.
