Following up to share that we have found a solution ourselves (no thanks to the customer support team at Zoom).
Registration needs to be enabled on Zoom as well.
To any integration users (e.g. Eventbrite integration):
- If your registrations on an external system are not longer being acknowledged by Zoom since the 1st of March 2022, turn on registration on the Zoom meeting/webinar (with no additional required fields, as these cannot be matched).
- This will mean Zoom no longer ignores the registrant information fed by your platform of choice.
- Once registration is enabled, you will once again be able to see:
- (A) registrant numbers leading up to your event on Zoom, and
- (B) capture attendee emails in your attendee reports.
The above is how you can comply with the first point listed in the March 2022 update:
"[...] you will continue to see email addresses included in your Reports and Dashboard for the following groups:
- If the participant entered their email address during the meeting or webinar registration flow, then it will be shown for that specific meeting/webinar."
It's very simple and should have been communicated to integration users much earlier.
For anyone worried about enabling registration on the Zoom webinar/meeting - this does not mean your attendee is asked to register on your platform of choice and then again on Zoom. It simply enables Zoom to use the registration information already collected by your platform.
