Webinar Recording Not Showing the Video

I've purchased the webinars in preparation for upcoming sessions.  I've been doing some prerecording with the camera on and when I go to play the recording, it only shows a blue screen, it only recorded the audio.  I double checked the settings and it has everything turned to ON.   I did a test with someone and they had said that they could hear me in the webinar, but could only see the general screen of waiting for host to start the meeting?  Has anyone experienced this and have a solution? I contacted Zoom support via email, had correspondence at first, and now it's been 24+ hours since I've had any follow-up.  TIA for your help!
