I'm using this on a Meta Quest 3. I tried to reboot the headset, nothing helped.
When the game first loads I see the logo at eye level. The moment I get to the menu, I can see myself suddenly getting tall. If I stand in the game, I see everything from above and the character has to really lift her head to look at me :-)
If I sit down, she's now at eye level more or less, but that makes some of the activities impossible. I tried to change the guardian, and I set the floor level correctly, but that doesn't seem to affect the game.
Maybe add something in the settings that would let a user reset the game's alignment with the guardian's coordinates? (or just have it do it automatically every time the game starts?)
