The site told me it was an ADB issue, so I installed the PC Advanced Installer and it's telling me that ADB is detected and good to go, but that my "Device isn't Authorized". It recommends checking my antivirus, but I've told it to ignore all folders with ADB and all folders with any SideQuest files, so... That's not the issue, I've already uninstalled and reinstalled the app, I've rebooted both devices, and checked all of my drivers.

The device not being authorized means that the notification isn't working right, seemingly. When I plug my Quest 2 in, I get a small popup saying to click it to authorize USB Debugging or similar, but then my laptop plays a sound as though my device was being unplugged and plugged in again (which can be normal, from what I understand) but then the app tells me that I still need the authorization. Not really sure why the authorization popup doesn't look like most other people's, but here we are.
