Not really as question but an advisory, the recent KB5070311 update is causing an issue in system| sound for detection of Bluetooth Headsets, after update if I turned my headset of then turned back on after a period of time it no longer engages and plays audio or shows until a significant amount of time has past where as before it was almost instant (within a couple of seconds) it would detect and show and be playing audio.

The update has introduced a significant lag in the detection, it still finds but it annoyingly slow.

I reverted the update and everything returned to normal.

    KB5070311 is an optional preview update, it is basically an early beta release of the December update.

    The optional preview updates can be hard to install sometimes, may contain bugs and there is no need to install the optional preview updates.

    If uninstalling that update resolved the problems, below that update is a switch to 'Get the latest updates as soon as they are released', disable that option and restart your PC, that will stop the optional update continually trying to install and wait for the full December update to be released next Tuesday.
