F5 Access 2018 app shows "Unable to retrieve network access configuration" on iPhone 7 with iOS 12 (beta)

Thank you. I will create a case with support now that IOS 12 is out. The issue is still extant with exactly the same conditions while using the new "F5 Access" app, version 3.0.2, from App Store.

In our access policy, "OTP Verify" succeeds when the user enters the PIN code from the SMS in the Web Logon screen, then the app displays "Unable to retrieve network access configuration".

The APM log says that our Connectivity profile was assigned correctly, and also "Access policy result: Full".

After that, the server receives client info and then logs "Session deleted due to user logout request".
