I have background video on my frontpage, but it is not seen on my mobile. I have same kind of video on other site, and there it works fine.
Thank you for the inquiry.
Please note that background videos are disabled on mobile videos by default, which is why a Fallback Image option is available. The fallback image will display on smaller screens in place of the video.
This is solved: the video was wbem-format. When I changed it to mp4, it is seen also on mobile. The wbem worked only on large screens
