Quest 1 not connecting to mobile App after factory reset (Headset Not Found) (MEGATHREAD)

[Realitias]

Hello!

I have a quest 1 that I used for a while and it worked normally. Yesterday I turned on app-sharing and added a second account to the headset and after testing something I deleted the second account again. After that, my Quest 1 was not showing up in the mobile App anymore for the main account. (wanted to enable Dev. mode again) I tried reconnecting (adding a new device), did a factory reset, installed the app, tried another Oculus account, tried another phone but it always displays this message [shown in the picture] after trying to connect vie the 5 digit code. Right now the headset is completely unusable because I cannot complete the initial connection to the app that is required. So I need a fix as soon as possible.
Thanks.

This issue is likely caused by residual account conflicts after enabling app-sharing.
Factory reset again, but remove the device from your Oculus app account first via the app or website.
Then reinstall the Oculus app, log in with your original main account, and pair using the 5-digit code.
Ensure Bluetooth, Wi-Fi, and location are enabled and permissions are granted.
If it  still fails, contact Meta Support directly—they can reset backend pairing issues.
