Hi there, for those that have tried the newer version of the firmware and didn't see any improvements, it turns out that you have to **power-cycle** (not just reboot) the machine after installing the newer firmware package. Some users even recommend pulling the laptop battery and letting it sit for a few minutes:
https://www.reddit.com/r/debian/comments/x0rfwu/psa_fix_for_ax200_random_bluetooth_headset/ I made a request to the Backports folks for the 20210818-1 version to be backported. This is a major bug in the Debian Stable version, so it would be great if it could be updated there too, but I don't know if the Debian Stable policies would allow that.
