BT is broken everywhere. I daily-drive MacOS, Windows 10, and PopOS, all on pretty solid hardware. All 3 have countless issues with BT stuff, whether it's UI and issues with connecting/remembering, or dropouts, or it just failing to work on random days, or audio glitches, or not finding some generic peripherals that the other OSes do find, etc etc.

I use BT a lot, half a dozen devices I use every single day, and I have issues with every single peripheral on at least 1 (usually 2) of the 3 OSes I use.

BT itself seems like such a simple thing to get right too... not sure what I'm missing about it that makes it so technically hard to just work as expected.
