I'm creating a new website, i used the background video feature to add a nice clip to the background, with full screen, 100VH. Background video is not working for tablet or mobile, so i added a background image for those, and tried to set the video to desktop only. But i can't get it working. Either the video still / pause image is displayed on mobile, or there's nothing at all. I tried to search for help for a fallback image, but couldn't find any.
Could someone let me know what i'm doing wrong, and what i'm supposed to do to get it working? Thanks!!
