When I create a modal window and insert text and a video, the video does not display. The same problem is on Modal blocks and on Modal Designer.
It’s a bit curious, because in Preview Mode, everything works perfectly. It’s only when I do a preview on a browser other than Safari (Edge, Chrome, Firefox), the video does not display.
This applies only when I want to have a video in the background.
On Modal Designer, no video is displayed anywhere.
