Our compnay has recently switch to MS Teams. We attempted to host a Town hall hoping to broadcast/stream the host presenting a slide presentation that front of the room on the large screen so that remote participants would have a similar experience to people in the room. Instead, the host was limited to sitting at a laptop while presenting and shairring his screen with meeting participants. There should be an option to share just your web cam in full screen, having congtrol of how it crops and zooms.
I can see how this will also be an issue when hosting project meetings where not everyone wants to be infront of a laptop. One webcam should be able to capture an entire group with each user having control over the number of feeds on their screen. If Google could do it in their collage software I'm sure Microsoft can do it here. Please consider issuing an update as I only see it as a win-win-for all businesses involved.
