We've had a report from a student that one page on our site isn't loading for them, and have verified this behaviour on both Android and iOS versions ourselves. We get the error:
Cannot connect: Verify that you have typed correctly the URL and that your site uses moodle 2.4 or later
We're on moodle 2.5.5 so that's not the issue. This is running the latest version of the app (1.13 according to the About menu on my iPhone).
I can provide a test login via PM Juan if you need that to debug why this one page on our entire site won't work in the app.
