Update:
At 11:00 AM the ITS team performed a test of the GridView extension version 1.36 that was released this morning. While the issue with showing attendees in a single column has been fixed, unfortunately we found that it has a new issue. Once the meeting hits 16 attendees, the browser crashes. We recommend NOT using GridView until this issue is resolved. In the meantime please use the Google Meet Native Layouts. This Knowledge Base Article explains how to use the Google Meet Native Layouts.
