We do support iOS 11. The client being on iOS 11 is an indication that the device has run our of storage space. Because it was out of storage, the files for our app were truncated because there was insufficient storage. A truncated file is there but it's corrupt. iOS doesn't detect this corruption, and the app is broken. Forever, and it can't be fixed without a factory reset, complete reinstall of the OS or somehow jailbreaking the device as far as I know. The customer reporting "stuck on a blank screen" and the User Agent being stuck on iOS 11, even when most people have automatic updates enabled are the primary indications that leads to this conclusion.
