I talked to M$ support about this a few months back (yes, that's how long this bug has been in Teams already). They wouldn't do anything to help, just insisted that I restart, clear cache, reinstall Teams, upgrade to the latest version of my OS, anything to give them an excuse not to actually fix the bug. They are completely useless and Teams is such a trainwreck of a product.
Since a month or two, I also can't make bulleted lists anymore in a Teams message. The first bullet is fine, but if I press Shift+Enter, the next line doesn't have a new bullet, and if I press Enter, it sends the message. No way to start a second bullet!
This is on top of notifications being broken on Teams for Mac (no red dot on your Teams Dock icon when somebody sends you a message, so I miss tons of messages as do my colleagues).
Then if you try to sign up for Teams (which sane people outside your company that don't use Teams will need to do to join your Teams calls), it doesn't let you use a plus e-mail address (e.g. ******@gmail.com) but if you try and put in an existing e-mail address it just tells you it already exists but doesn't give you a password reset option.
Compare this to how easy it is to set up a Google Meet call and share the link with people.
Sorry for the rant, I'm just SO frustrated by Microsoft's complete FU in the face of its paying clients.
