We have created a user macro , where we have included video url with Iframe.
We are able to see page with video. But when we try to edit and click on preview, the video is not shown.
If the video is youtube it is shown in preview. If the video is from our internal video library then we are not seeing the video in preview mode. If we save the changes , then we are able to see the video in page.
So issue is that we are not able to see a video in preview mode once after editing the page.
