TouchID settings removed when upgrading to iOS 12.1

Issue:

iPhone 7 / iOS 12.1 not saving TouchID Settings

Details to reproduce:

Upgraded to iOS 12.1 (from 12.0) and Monzo app was allowing access without asking for TouchID.

All TouchID related settings were disabled.

Paying around to try to recreate, I’m not sure if this is related or by design but when I exhausted the TouchID authentication attempts and logged and then re-logged in via the magic link. Settings had defaulted to not requiring TouchID to authenticate. (Possibly by design but I’ve not noticed this before).

OS: iOS 12.1
Device: iPhone 7
App Version: 2.22.0 #475
