I just finished my website on WordPress:https://ypsometro.com/

It remains me only one problem.

I have added a video on the homepage slider.

On desktop everything is OK.

The issue is that when I inspect with Google chrome, I can see the video being responsive and being displayed on mobile and Ipade.

But when I go on a real Iphone and Ipad the video does not show and I only see the static picture (the first frame of the video).

Any idea how to fix that?
Thank you so so much,
