The information for attendance is pushing over fine for single meetings, however, it does not push over for ongoing or repeating meetings. Is there something we need to do to make sure this happens?
Have you already tried resyncing all data from specific Zoom meetings, as described in this article? Does this pull in all the data?
If this won't solve the issue or if this is happening with all ongoing meetings, I recommend to create a ticket for our Support and include links to contact records where the Zoom attendance data is not syncing correctly. The team will be glad to have a closer look at the data in your account. Thank you!
