When I click on my calendar inside teams it sometimes just goes blank for about 15 seconds. When I open a link on teams it opens in edge despite edge not being my default browser, because teams has its own default browser settings. When I make a numbered list in teams it indents 1. but when I enter onto line 2. it indents it slightly more so the number don't align and I cannot undo this and I have never found out how to stop it happening. When I open an excel spreadsheet link in teams it opens it in a janky teams view, instead of Excel, the only truly great Microsoft app. When I insert a code snippet in teams I can sometimes exit it out of it by pressing down, sometimes not, and I just have to send the message and continue writing in a new one. If I start teams on anything other than my work machine there's a 90% chance it won't work and I'll be better off using the Web view. These are just everyday off the top of my head annoyances.
