Remove symbol from teams chat

[DeirdreON]

I have hit a few keys and now have this annoying degree symbol in my teams chat window (it doesn't send when I message anyone, but stubbornly remains in place). How do I get rid of it?

Try the easy thing first, restart the client :)

@Vasil Michev D'oh! Yes, I thought I had done that, but it turns out I hadn't. Just did it now -and symbol is gone :) Thank you.
