You must be amazingly lucky. Bluetooth has been nothing but issues for me for 15 years of use, across a plethora of host and client devices, OSes, mobile and desktop, all Bluetooth versions, proprietary implementations (game controllers), cheap devices, expensive devices, ranges, etc. Bluetooth has improved a lot in the past 5 years, but it's still not good enough imo. A PS5 controller can't stay reliably connected to my steam deck that is docked by my TV while I am sitting on my couch, yet an Xbox controller with a wifi-based USB dongle works fine.
