I am developing an app in UE4, which involves use of the browser plugin, and sites load no problem on Windows, MacOS and Android, but on iOS, some sites load in the browser plugin, while others don’t. I can’t see any rhyme or reason for this. Some http sites load, others don’t. Some https sites load, others don’t. And before anyone suggests it, I am OF COURSE using a full url with http(s)://
The iOS device I’m testing on is an iPad Pro with iOS 11. Just to reiterate, the web browser widget plugin IS working, and some sites DO load, just that not all do, and there doesn’t seem to be any correlation in which ones load and which ones don’t.
