Additional features, settings, or issues not covered by specific Microsoft Teams categories
I am experience the same exact issue with Mute button not staying on in Teams. I've tried closing Hub software, I've stopped the Plantronics services in MS Windows Task Manager, nothing helping. Still having the issue. Zoom and Webex meetings seem to work fine.
This is very disruptive and potentially dangerously embarrassing for headset users. This needs to be resolved by Plantronics ASAP to protect their reputation!
