How to disable on mobile phone

There is no direct way of deactivating the plugin just when accessing the website via mobile. My suggestion would be to use a “responsive CSS” approach instead. Eg by adding something like this to your theme’s CSS file:

@media screen and (max-width: 800px) {
  ul.relatedYouTubeVideos {
    display:  none;
  }
}

I’m also not a 100% sure about why some mobile devices don’t work so well. But it might have something to do with the HTML this plugin is using for embedding the videos. Currently, it’s using the <object> approach. Maybe using <iframe> might get better results for mobile. But I’m still researching that.

Thank you very much ! Worked ??
