Cannot login to Box on iOS 11
Hardware & Software: iPhone 6S with jailbroken iOS 11.2.1 and VLC 3.3.10
The problem: Clean install VLC from App Store, open it and try to login to Box, enter correct information, click "Authorize", then the login page refreshes and immediately jumps back to itself without any error or further verification requirement. Tried to enter wrong e-mail address and password, the page again just refreshes itself and jumps back without messages like "invalid user or password".
Box web app is working fine in Safari on the same device, so maybe Box API login page is broken on iOS 11 webview framework.
Got this screenshot of the login page, seems like something is actually broken, for example the large logo is probably misaligned, and the links "Terms of Service" and "Privacy Policy" lead to a "blank" page:
