I've only tested it on iOS 9, yes. And it's not a problem with the
iframe not loading when offline, that's a given. It's a problem that the
entire article won't load and simply exclude the iframe content. And
yes, it's all iframes. In DPS 2014 when things like this would happen
with an overlay we'd usually have some text that would state, this
feature requires an Internet connection. But I can't get anything in the
article to load, it's just a white screen.
