Bluetooth Headset not supported for macos Monterey

I thought you had just thrown up your hands in defeat. I would look further into this but haven't found a BT debug tool yet. This problem seems so prevalent that it gives you pause about Apple's test bucket for OSX 12.

This problem is peppered across the forums. I've tried all the suggestions and none have worked. Even a set of headphones that do work ... don't work every time I connect them to my iMac.
