Video background doesn't play on mobile

Hi, the video background doesn’t play on mobile.

Ok, maybe it’s not possible to resolve this issue. But, normally, we can use the Placeholder option to display a single image instead of the video if it’s on a mobile.

I dont want to have to erase the header on desktop beacause the mobile can”t display it correctly. I also tried to remove the content only on mobile but it’s only possible for the content inside the row and not on the row directly. then on mobile, i still get a huge grey background and that’s really cheap.

I can’t imagine there is no solution for that.

thanks for your help.
