Introducing Microsoft Teams Rooms (Updated)

Petri-X , Teams web client updates will work with existing app store verion of the application. I will be posting a detailed blog post for everyone to understand MTR releases soon. But in nutshell, there are two release trains. Store app (which is the version mentioned in TAC) which is the main application which contains SfB, Teams, 3P client to join Cisco/Zoom meetings and device agent for TAC communication/ device mgmt. Everything except for Teams application is updated through Store app. Teams is a web application and uses same mechanism as Teams desktop for updates. Features within Teams are released using web client update, and have been for couple of years now. If a feature doesn't have any app level UI (e.g. app home page, settings etc.) it doesn't need store app to release at the same time and will work with existing store app. We are working on enabling Public Preview for MTR store app and web client features for customers to try out these features and provide feedback before they are rolled out to GA. Again, expect more concise documentation around this soon. 

For video crop issue, after you verify, please submit a support ticket. We now use the same gallery component as Teams desktop, so it should not be isolated to Teams rooms only, and we can take a look at this and get a fix for both Teams desktop and Teams rooms sooner since the impact of such change will be too broad.  Hope this helps!
