YouTube Video disappears on mobile

Hi,

thanks for that great tool. ??

The plugin works fine with Divi Builder and YouTube on desktop version of a website.
But, when i resize the browser window to a small screen (like mobile view) or take a look at the page on a mobile phone, the video disappears on the page.

This is just with activated plugin; when i deactivate the plugin, the video is shown on the page as it should.

Thanks for any help or hints.

Regards,
Ray
