Zoom meetings getting deleted from Outlook calendar

[NoIdea89]

Im seeing an issue with prescheduled zoom meetings where the meeting time itself will show up in MS Outlook, but the link within fails with the message "Invalid meeting ID" . The zoom meeting controls on the right of the screen then say "The Zoom meeting is removed from Zoom web, If you want to add a new Zoom meeting to this event. please remove this meeting." -or- "Your scheduling settings have been synced from your zoom web portal"

This is a recent issue that has come up, and I have rarely (If ever) used the web portal vs just using the zoom app.

It is only some and not all of scheduled recurring meetings. 

Has anyone else seen this or have some tips on troubleshooting this? 

I can easily make and resend a meeting invitation. But the issue happens randomly and a few on the meetings are high priority so I need to ensure they are working. 

Zoom is up to date on my device.
