We are running a learning management system, we integrated our system with Zoom. We have some webinar courses, users need to purchase course to join in webinar. After launching a couple of webinars, we have an issue about Zoom attendance report. Basically, users will purchase course, and after purchasing course they will have a Join URL to join the webinar. We use the user’s email on our site to register user with Zoom. Users don’t know about the webinar registration URL. In recent attendance reports, we see there are some users having two emails in the report. And some emails that did not exist in our system.
For example: User A has the email email@example.com in our system, he purchased the course and join the webinar. In the attendance report, we will see
user_a@gmail (not attended)
(these two emails are from the same person)
We still not figure out this situation. Please advise. Is there any chance that user A used different devices to join the webinar?
