The solution I’ve sort-of found is to go to communities of Arch-based systems instead of Arch itself. The same solution should work in most cases*, and the communities are more newbie-friendly.
*Depends on how close to Arch the distro is in this aspect/subsystem. The Manjaro community is probably less likely to offer AUR based solutions, since the AUR can be unreliable/unsafe on Manjaro.
I’ve had issues since kernel 6.4. Since early December, one pair of Bluetooth headphones works again (mostly, with occasional connection issues), but the AirPods still fail to pair at all.
