Known Issue: Upcoming iOS 11.3 release
As a Pega Mobile Client user, if you upgrade to the iOS 11.3 or iOS 11.3.1, you will discover that you cannot log in the application.
This impacts all Pega Offline, and Pega Online applications that use cache manifest.
This will be an inconvenience until Apple releases iOS 11.4. Apple has confirmed that the bug is fixed in iOS 11.4.
If possible, do not upgrade until iOS 11.4 is released.

***22/05/2018: Updated by moderator: Lochan to edit message content to remove information that states that you will be able to log in to iOS 11.3 application on subsequent attempts***
<30/05/2018 edit> iOS 11.4 is now LIVE
This has been reported by Pega to Apple as Bug: 38505756, and thanks to Pega, Apple fixed this bug in iOS, but the fix will be available in iOS 11.4
Pega Mobile Online applications are affected only if using cache manifest.
Pega Mobile Offline applications are affected, and will not work offline at all.
Technical details:
When login in, even though Pega application properly authenticates the user, WKWebView does not send cookies along with cache manifest request and all the requests for resources listed in it. Because of that, application cannot be properly cached and installed. This is a regression comparing to all previous versions of iOS.
