Youtube video not showing up on iPad or iPhone

Have your plugin used here on this site – https://www.caraghprecision.ie/

The homepage video link opens a YouTube video in modal popup.
This does not work on Apple devices (iPad and iPhone). The video does not display.

The modal windows will work on other pages to display text or images
(like testimonials link here in sidebar on https://www.caraghprecision.ie/products/vascular-structural-heart/).

Can you advise if we need to set any specific settings or use any specific code or amend the plugin code in any way to resolve this issue?

Thanks
