We have the same challenge, but believe this is the situation. The reporting offered in Zoom Meetings vs. Zoom Webinars is different. If you host as a Zoom Meeting you cannot pull an attendance report!!!??? Meeting options for reporting are limited to registration & polling. This is very frustrating! If hosted as a Zoom Webinar, however, your reporting options include Registration, ATTENDEE, performance, Q&A and Poll Reports.
We want participants to be interactive and have cameras on so we need to host as a Zoom Meeting. We are very disappointed to see we need to take a screenshot for each of our Zoom Meeting events to have some kind of way to capture attendance!
