Formatting is annoying in Teams but I've mostly learned to work around the issues. My number one annoyance, that doesn't seem to be mentioned that often, is that there are many places where you can't get a direct link to a message. I get a huge volume of activity in teams, and there are many things I need to bookmark for later action that would be too challenging to find again. Most of the time, I can't right click and save a link, although sometimes in the web interface it's enough to copy the url. Providing deep links to any message in teams is my number one feature request.
