Chat options not available - Teams App for Mac

I have been trying to fix this issue for months. Uninstall, clear cache, reinstall, nothing has worked. I click on links to join meetings only as a visitor (I do not pay for the app, the other party does).

Also, each and every time I try to join a meeting now, the option to click on "already have Teams...?" does not respond, so I have to re-install it each and every meeting. I can live with that, but I cannot work without a chat box.

I have had no real help from Microsoft. It takes about an hour to explain the issues, and they seem to know less than I do. Nothing fixes the problems.

Apple tells me that there are many issues with Teams for Mac users, and they have yet to be fixed.

What is also strange is that I used to click on the "already have Teams", it worked, AND I had a chat box for over a year and a half! (and yes, everything on my Mac is up to date)

I guess the only solution is to ask those who provide me with work to use Zoom, where I have never had any issues whatsoever.
