Additional context

Tried many things as suggested in the readme and the issues sections. Tried to play music and then connect. Granted Nearby Devices and Bluetooth access, enabled Notifications in the system settings, allowed Battery Background Activity, toggled on High Background Power Consumption, allowed the app to Display Over Other Apps, unpaired and forgot the AirPods in Bluetooth settings, cleared cache and data for the LibrePods app, used the Quick Settings Bluetooth toggle trick, tried the reversed launch order with music playing, reset all network and Bluetooth settings on the phone and rebooted your Oppo Find X9 multiple times.

Nothing has worked. Kindly suggest any help.

The issue names no source file, test, or entry point. Begin by reproducing the initial-handshake failure on an Oppo Find X9 with ColorOS 16.0.9 and collect the missing logs; done means the cause is identified and the AirPods connect through the initial handshake on this device.
