There isn't anything in particular that changes about the Bluetooth level behavior of WearAuthn when single-factor mode is enabled.

I think that this is an instance of a more general issue that is unfortunately inherent in the design: Most Bluetooth stacks don't handle devices well that dynamically change their Bluetooth identity (e.g. between sound/keyboard/mouse). I have had similar issues in the past, especially with Windows hosts, that required multiple resets of both parts of the connection to resolve.

I reset my Watch and it now works again even when it is displyed as an microphone.
