Still not working for me. I'm using LG Gram 16, tried to uninstall bluetooth drivers, disable automatic download for Windows and install it through LG Update - it downloaded 20.150.0.6 version so the older one, which after uninstalling headphones and pairing again changed behaviour - now, sometimes it says it's connected but no microphone or headphones are detected, and sometimes hands-free headset is detected only, so microphone is working but sound is very poor.
After that, I firstly downloaded and installed 20.160.0.4 version, and now I've installed 22.230.0.2 version, so the newest one. The behaviour didn't change, so only hands-free headset is detected now without headphones..
