Hey there, dominuselitusyt. We can definitely understand how concerning it would be for your Quest 2 to not pair correctly with the mobile app, and we'd be glad to look into this for you. We'll list some troubleshooting steps below for you, give them a try and let us know how it turns out.
- Ensure the phone's Bluetooth is turned on and the headset is turned on.
- Ensure the app and headset are using the admin account, and not an additional account.
- Clear the Bluetooth cache on the phone. (see below)
- Power cycle the phone and the headset.
- Power off and then back on again. If unable to power off the headset normally, hold down the power button for 30 seconds.
- Uninstall and reinstall the Oculus application on the phone.
- Ensure the phone and headset are connected to same wireless network.
- If using a dual-band router, also make sure they are connected to the same band (2.4 GHz or 5.0 GHz) as well.
- Try using a different phone.
- Factory reset the headset.
Bluetooth information may vary from device to device.
