I am having an issue with the top level nav not appearing when the screen is tapped. In my case I have narrowed the issued down to pages with an embedded Youtube video (using the Youtube iframe snippet). It's specifically an embedded Youtube video, I've used other sources for the iframe and the nav works properly (as it does if I remove the iframe entirely). I've also tried removing all javascript to remove any potential conflicts and get the same problem (actually, I just tried with an article that was only the video and the nav didn't work). Any help would be greatly appreciated.
This issue is only on iOS devices, everything works perfectly on Android (currently testing on an iPad running iOS 9.3.2).
