Provide the name of the program you are using so a Moderator may move this message to the correct program forum
This Cloud forum is not about help with program problems... a program would be Photoshop or Lighroom or Muse or ???
The program I am using is Kizoa to develop the video but I can't imagine that this is the problem. I create the video in Kizoa and upload it to YouTube. At that point the slideshow on YouTube is working perfect both on my cell phone,PC and Tablet. The YouTube version is working fine even on my cell phone. At that point all I do is copy the link URL from YouTube and, using CC, place that URL into the page you see on my web page. It no longer works from my web page on a cell phone but still works perfectly on my PC and Tablet.
Sorry, I just realized I didn't mention that the program I used to place the YouTube URL on my site was Dreamweaver.
