Hello Cathy,
My name is Veejay, an Independent Advisor and a Microsoft user like you and I'll be glad to help you.
If you want to see participants video, you need to enable "Turn on new meeting experience" on Teams.
- At the top right of your app, click on your picture > Settings.
- Under General, enable " Turn on new meeting experience (New meetings and calls will open in separate windows. Requires restarting Teams.)"
- Restart Microsoft Teams by right clicking on the icon > Quit then start again.
When a new meeting started, you can click on More options (...) then select Large Gallery View to see participants. You can also see there the meeting chat options.
Note: This view is available when there are 10 or more attendees who are sharing video.
