That does not happen, even with the beta grade Linux version on Arch (as I run it)
You may have a rubbish internet connection. If you are using a VPN with a slow internet connection, investigate a split tunnel. Teams traffic involves only three IP ranges so it is easy to split out and route direct to shave a fair bit of latency.
Other issues will require more investigation but they are local to you.
I'm only 50 and been messing around with them for about 40 years.
My point was that even on a precariously supported platform (my Arch Linux computers), the software works fine - ie as proscribed. MS Teams is used by a vast number of people and has a habit of working OK for them.
Same freezing problem, company issued laptop 100mbit internet connection. Same feedback from hundreds of people. Half a gigabyte RAM or more even when Teams inactive. Other softwares have solved this problem so I will agree with the opinion that Teams team should put their act together. I will postpone prioritizing Teams ips to the routers.
