Bluetooth Monterey Not Connecting to iPhone and Other Devices

Apple has six hours of my life that I'll never get back trying to resolve this. Four hours on the phone and two hours in the store. The store representative ACTUALLY said, 'iPhone and Mac normally do not connect using bluetooth'. Well, I've been connecting (and using and needing) this bluetooth connection for years. Five Apple representatives and they don't have a clue. To their defense, they reset everything they could. BTW, if you think you can just go back to Big Sur to get your Bluetooth back, it isn't so easy. 

'I am also having issues connecting iPhone's via Bluetooth since upgrading to Monterey. It will Pair but will not stay connected. I also have received the message: " MBP is not supported" when attempting to connect directly from an iPhone. I did not have this issue on MacOS Big Sur (11.5)

I have tried connecting with the following on three different Intel MBP's all running Monterey (12.0.1):

• iPhone 7P / iOS 14
• iPhone 8 / iOS 14
• iPhone 12 / iOS 15

I have attempted to correct the issue by following multiple suggestions:

• Reset NVRAM
• Reset SMC
• Remove .plist

None of the recommended steps are working - hoping that Apple is all over this and will be releasing a fix shortly.

It would be helpful if a Moderator would acknowledge this as an actual issue that Apple is actively working to resolve or if I need to restore Big Sur to make this work again.'
