I remember Apple having scads of Bluetooth problems in the first ~5 years, and then off/on problems for 10 years. These days I pretty much expect it to work. The problem on Linux with Bluetooth is there's multiple kernel drivers involved, one or more daemons, and one or more interface tools. Knowing which component to blame for a bug, is not obvious. Learning about components is tedious: btmon, btattach, hciattach, hcitool...it just goes on and on. I've filed bugs about random bluetooth mouse disconnects, and it gets blamed on some other component where there's no response from maintainers for basic questions like, how do I get you more information? Things like hcidump will get you metric f tons of information about the connection, way too verbose (dozens of lines per second) but zero information about why there's a disconnect. And in many bug reports I see maintainers blame hardware, even when the problem doesn't reproduce on Windows 10. I'm sure it's quite complicated, but there isn't even a decoder ring for how to help users file useful bug reports.
