2/15/22. I have been waiting for this fix for two months now since I upgraded my MacBook Air to Monterrey. Just downloaded 12.2.1 hoping that Apple finally fixed the Bluetooth issue. I cannot get on bluetooth at all. I have done all the recommended things with the Plist files, shift, option bluetooth to no avail. It says blue tooth is undiscoverable. I am glad I tried this on my MacBook Air and not my new MacBook Pro. I am not going to download Monterrey to my pro unit until this issue is fixed. COME ON APPLE, I haven't run into anything like this since I switched from windows based years ago. AT LEAST SOMEONE SHOULD GIVE US SOME FORM OF EXPLANATION

I recently downloaded Monterey on my 2017 MacBook Air. It has prevented bluetooth from connecting to anything and the icon is greyed out with a line through it. I have tried the varied fixes that I found on line but to no avail. I am hoping that Apple will quickly put a fix in a future update because this is an extremely annoying problem for a large number of Apple fans.
