This issue needs to be tested in 1 Android and 1 iOS device. Basically the behaviour should be almost the same in Android vs iOS, and in local iframe vs online iframe. I already prepared a SCORM (local iframe) and a custom main menu item (online iframe) to test this, they're in our master site. In the app, login in our master site and open MM Dev Testing course > SCORM > SCORM with links _top, _self, etc. Clicking each link should do what the link already says. E.g. if the link says "opened in same iframe", then the new page will be loaded in the same iframe, if it says "opened in app" then it's opened in a new page in the app, etc. The behaviour should be the same in Android and in iOS, with minor differences like the "popover" which is different in iOS and Android (in Android it uses the embedded browser, in iOS it uses a native viewer). Now go to More tab > MOBILE-4018 : Iframe to test open links. As before, clicking each link should do what the link already says. The behaviour is almost the same as in point 2, except that the first section in SCORM is "Local file" because the app is loading a local file (a file downloaded in the device), while in this case it's "Relative link" because the page opened is online, that's why the behaviour is different. But the link already says what it should do.
