@windows10insiderag,
Please don't make the assumption that we don't know how to troubleshot some of these basic issues. While this issue has gotten better over the past year, there remain issues. I have used 3 different cameras. My home wifi is over 350 mb/sec and am sitting 2 feet away from the WAP. I am both on and off of VPN's. While at home I have no control of Verizon's infrastructure.
Our early research found that the biggest issue was that Teams did not play nice with the Microsoft Surface machines. I have Surface Book 2 and that was a particularly notorious problem. We were experiencing lag over 30 seconds long when sharing a screen.
Thankfully we have not experienced this level of difficulty recently but there are still issues and these should not be pushed back onto us as users. We do understand that this platform is developing rapidly and it should also be understood that this is the venue to let Microsoft know the issues their users are seeing.
