A light theme please
I cannot communicate enough how much dark themes INFURIATE me. Let me say it again I HATE dark themes. There was a time I could select my own theme for windows based Apps, we don't need to go that far, but for every Microsoft should be able to share the themes used by Office.
Despite choosing the default scheme (defined as light) the call window is all black (including the participants list and the chat section) which makes my eyes get sore in 5 minutes((((.
