I’ve had bad results on Mac OSX as well.

It’s partly a timing thing, and maybe that puts the issues in the apps. If I am using my headset, it also works in things like Teams and Slack. However audio doesn’t want to switch if I turn in the headset in the app. Even worse, if I turn the headset on right before launching a call. It’s better now that I turn in the headset, then do a slow count to ten before starting a call, but still not reliable
