Videos not working on mobile

Hi,
thanks for your plugin! I’ve used it on a site that I’ve done for an association.
I’ve discovered that videos (embedded from vimeo) doesn’t work. In smartphone and tablet, android and ios, the gallery shows only a screenshot of video box.
I now that the plugin gives problems when are lots videos on a single gallery, but this is not the case because I usually have only 1 video and few photos in each gallery.
On normal pc and browsers all works correctly, you can see videos and images, only on mobile videos became images.
Do you know what’s the problem and what i can do to solve it?

You can see an example here: https://www.reneis.org/it/toponimi/la-vio-des-coste/

Thanks!
Martina
