Live Event engagement report - blank participant ID fields

Hi PeterRising,

Thank you for your quick response! I also found the URL that you are describing, however the strange thing is that the live event in question is set as an "org-wide" event, so the attendees should have signed in to be able to join. I also checked the "Attendee engagement report" checkbox. Still I get these blank Participant ID cells in the Excel. I heard rumours of the call API malfunctioning in these cases, can you confirm that or is there a better reason to explain this?

Thank you and with kind regards,

Sylvester
