Microsoft Teams Rooms July Update

Paul Youngberg Thanks for upvoting multi-camera support on user voice. Multi-camera switching in Teams and other Video camera features such as PTZ options are in plans for later this year. We expect these to land early CY2020. 

To answer your question on Layout button in meetings call controls, this is used to switch between Gallery+Content or Content Only layouts in case of single front of room display. The control enables when someone in the room or a remote participant shares content in the meeting. For dual front of room setup, the button changes to switch screens to enable swapping content and gallery screens between two displays. We plan to add more layout options in the future. 

People gallery today is dynamic and shows 2x2 grid for participants, this will be refreshed to 3x3 in future and will add more controls like spotlight and options  to pin participants on front of room display. Please stay tuned.
