Hi Vincent,

We haven't made any major changes to Team Workspace and video chat since we released the changes in Build 6911.  Whether you create a new meeting or enter an existing meeting this is the screen you should see:

To get the link for the meeting to share with others click on the Settings icon in the upper right and locate the Meeting Link card.  You can also add a password, allow guest users, adjust video settings, and delete chat history from that screen.

Let me know if you're seeing something different.
