Pre-recorded video not appearing in webinar recording in new app

My webinars typically consist of live intro, followed by a pre-recorded video (which I upload prior to the start of the broadcast), followed by a live Q&A session and outro. I have also programmed the backend to automatically record the webinar once the broadcast starts.

 

Using the old version of the platform, my recording would capture everything, so I'd have one webinar recording consisting of the live intro, the pre-recorded video, and the live Q&A and outro.

 

I have used the new version of the platform twice now, and each time the webinar recording does not capture the pre-recorded video that I shared during the broadcast. The webinar recording does run the full length of the webinar itself, so comprises the live intro, then the default GTW microphone background image spanning the length of time the pre-recorded video was playing, followed by the live Q&A and outro.

 

During the webinar I play the pre-recorded video using the Share button at the bottom of the Control Panel.

 

Is there some step that I'm overlooking to make sure the pre-recorded video is also being capture in the webinar recording?

 

Cheers,

Donal
