Registration report for yesterday's webinar is not showing

Hi,

I'm not able to find the registration report for a webinar that occurred yesterday. I made sure to check the date range and also looked for it via the Webinar ID but still nothing. 

The reason why I need the registration report is because it looks like the attendance reports now don't show the registrants who did not attend. 

There is a possibility that this information was lost because I had to remove the registration requirement of this webinar in order to allow the panellists to join (panellists having issues receiving invitations from Zoom too). Sorry, it's a mess but if anyone is able to provide some suggestions, it would be greatly appreciated!

Thanks. 

Sharon
