video - Black screen on mobile


I am trying an interactive video which works great on my laptop with chrome.  However, when I try it on my mobile device (iphone 5) I press play on the video but it is just black with the sound playing


i have tried this with both safari and chrome on a mobile device.

images attached

Any help would be much appreciated

Hi damianbarb,

This looks like compatibility issues with the browser installed in Iphone 5. We only support the 2 most recent versions to make sure that we have all the features available to all content types.
