The last few updates really seems to have made the Quest 2 finicky. I really like the system when it works, but their software updates have really been crappy lately as far as I can tell.
First of all, when you start it up, does it find your Guardian boundary ok and tracking is ok? Assuming that's alright, try this:
1) Plug it into the link cable if it isn't.
2) Close the oculus app on your computer.
3) Hold the power button on the Oculus and choose restart (don't power down and power up) the headset.
4) When it comes up, it should ask you to allow data access to the cable.
5) It should at this point ask you if you want to enable Link. Click yes.
6) Start AH.
7) Click Yes to "Do you want to use your Oculus".
Yeah, that's what I get to do every time I want to play AH.
When it works, it works well for me, but in the last couple months I've had issues (confirmed from various sources online) where it would lose my Guardian boundary every time I tried to use it and I would literally have to do a factory freaking reset to fix it. Then it would work once, then I would have to do another factory reset the next time I wanted to use it. If it's having trouble finding your guardian/tracking, you might have to do that to resolve it.
The hardware's pretty decent but their software appears to have been created by a guy sitting under a bridge huffing gasoline and talking to a pool noodle he's drawn a face on when he has a question.
