We are working on supporting more than 4 videos in a Teams meeting. We don’t have a date to share, but will update as we get closer to completion.
For multiple people in a call, it is also helpful to be able to chose if you want just one of the video screens to dominate. For example, someone may be showing a prototype or may be pointing to a status board.
Sometimes you want to see everyone. Sometimes you just want to see one.
