I have a Storyline 3 course with a Vyond video embedded as MP4. The content is designed to be taken on a mobile device. I tested it on my iPhone. The device DOES NOT auto-lock (a.k.a. go to sleep) when watching the Vyond video, but it DOES go to sleep when watching a slide with content built directly on the timeline. Any idea why this happens? I don't want the device to go to sleep at all. Thanks for your help!
