With the grid view you can see multiple guest on the main screen, instead of seeing one in the main screen and the others in the side bar on the right.
How does it work?
With two or more guests in your video meeting, the grid view will be automatically selected. If you want to switch views, you can click on 'view' in the upper right corner.
You can choose between a focused view and a grid view. With a focused view you will see one guest on the big screen and other guests in the right sidebar.
If you or the guest is sharing a screen, the shared screen will displayed as a separate screen and not be included in the grid view.
