Greetings and hope you have a good day,

I'm writing to let you know about an issue with using the MX master 3 mouse with MS Teams.

The default setup of the side buttons is to start/stop a video with the forward button and to mute/unmute the mic with the back button.

When I have the window of a call selected and use the buttons, the only thing that happens is to open a window with some PC stats after pressing the forward button(please see the attached .png for what exactly is shown).

The side scroll wheel, which is setup to adjust the volume works as intended in the same test case.

Hope this is helpful in some way.

Have a great day,
T. Solarov
