video has no play button when first loaded in iOS
I'm fairly new to Storyline, and I'm trying to debug an issue.
If I publish my project with HTML5 enabled (Mobile Player disabled), then view the project on an iPad (running iOS 9.1), it all works well except for when I get to a slide with an embedded video (it's an mp4, if that helps).
The video loads, but there's no play controls visible when the page first loads. I just see a completely black box in the screen. If I tap into the black box, the video starts playing and the controls appear. But I'm concerned about users who don't know that there's supposed to be a video there and don't think to tap into the black box.
On my desk top computer, the same slide loads with the play controls showing straight away.
What am I missing?
