I think I found a solution. I am not working with one of the templates, but I built a site with two versions, a desktop and phone. On the phone version my Video a Youtube URL Widget would not autoplay, I couldn't even click on the play button, I noticed I had built a solid in front of the video widget that had a stroke only. I think this was causing an issue. I sent the stroke only solid back one layer behind the video and turned off autoplay. Now on the mobile version the video shows up, and I can press the play button to get it to play. Hope this helps.
