Marketo Integration sending incorrect attended/no show status

[lisam2024]

We use the Marketo and Zoom api connection.  After the Zoom Event concludes, Zoom should report the status of each person that registered as either "No Show" or "Attended Live".  For the past 6 months, Zoom has reported all registrars as "No Show" except our internal team.  The internal team includes the event creator and panelists.  In order for Marketo to have the correct program status, we have to manually refresh the data from Zoom.  After the manual refresh the "No Show" and "Attended Live" status are updated and corrected.  

All of our lead routing and post event emails are trigger based.  We need the correct post event processes applied to the correct status.  Any help would be greatly appreciated!  Why is Zoom not pushing the correct attendance data the first time?  How can we fix this issue?
