Client getting constant Update Required notification

[Zoom91]

I work for an MSP and we have a client that gets a frequent Update required - You must update to the latest version of Zoom to join this meeting.  Contact your IT admin to update screen.  We have tried multiple times to uninstall Zoom and re-install the latest version.  The update screen always come back.  The last time we tried the re-install we made sure to check the auto update box.  Screen came back.   We checked with Threat Locker, and they did not see any instance that Threat Locker is blocking the auto-update.  If she tries to join from browser it doesn't allow her to join.  

I was wondering if anyone had any suggestions?  Thanks!
