YouTube autoplay won't work on mobile

My YouTube videos won’t autoplay on mobile even though - the video is muted and on autoplay, and my phone is not on power saving mode.

Here is my site Read-Only:

Autoplay videos are in the ‘Home’, ‘Services’ and ‘Contact’ page

I would like to know this too. It works perfectly on the design interface but not on my phone. Any help is appreciated x

I’m looking for a solution to this issue as well
