In some cases, your Google Workspace admin may have disabled Google Meet as an option for all users at your company.
First, check to see if you've chosen Google Meet as the video conferencing option for your link meeting.
Navigate to Links menu > Edit link.
If so, reach out to your Workspace admin to enable Meet support to confirm that this meeting platform has been disabled. If so, it's advised that you alternatively connect your Zoom account to Clockwise, and use Zoom for your Links meetings.
