Post-Webinar Survey Not Automatically Displaying for Some Attendees

[SEMJMC]

I always attach a survey to my live webinars and have had some attendees say that the survey did not display when the webinar ended.  Last night, 80 of my 100 attendees completed the survey immediately following the webinar.  I have heard from at least 5 people who said it did not display.

Any ideas what could cause it not to work?  Pop-up blocker settings?  Firewall settings?  

Thanks.

I believe the survey only works if the attendee uses the Zoom Desktop app and it has to be version 4.0 or higher.  I am not sure if it works with the mobile app. Is it possible some attendees attended using a browser or older version of the app?

Thanks, Chris!  It is a very good possibility that this is the case.  Thanks for the help.
