Additional features, settings, or issues not covered by specific Microsoft Teams categories
I use Edge for MS Office and I'm also getting this pop-up that the Chrome users are getting. It occurs when I have a live meeting on one monitor and I drag another tab for chats and teams over to the other monitor. The pop-up seems to occur in whichever window is not active at the moment. If I'm active in chat for a few minutes while the meeting plays the pop-up happens in the meeting tab. If I'm active in the meeting window for a few minutes the pop-up happens in the chat tab. After reading this, I'm assuming this is by design and the application simply is not designed to have multiple connections open and operate on multiple screens via browser.
