Google Calendar add on Failure to create meeting

My Zoom add on for Google G-Suite Calendar is no longer creating meetings. The Zoom drop down option appears on the main event creation screen but I get a "failure to create meeting" message. I've uninstalled and re-installed add on with no effect. All GSuite-Zoom access is granted. I am the administrator for our organization so permissions are not the issue. I saw this elsewhere in the community with no reply. I am using Edge browser, GSuite Calendar, Zoom add on.

I use this all the time so all suggestions welcome! Juliet
