Hi @tommy,
Do you have an update on this issue?
Our current workaround is to use the registrant email for registration required meetings to map to the original registration and it works for 90% of cases if they login Zoom or not, but if they login Zoom with a different email it obviously doesn’t work.
The fix would be to simply emit the original registrant id even if they don’t login Zoom to join the meeting.
Let me know - thanks!
