[iOS App] SN won't trigger biometric scan automaticly while using the app switcher

[MustachedMario]

Describe the bug
SN triggers the biometric scan automaticly when authentification is needed, but if you open the iOS app switcher by swipe-up and don't switch to an other app, but reuse the already opend session, the biometric scan isn't triggered automaticly.

To Reproduce
Steps to reproduce the behavior:

1. Open SN with enabled biometic scan (face id in this case)
2. Biometric scan is triggerd, continue by pressing 'submit'
3. Open the iOS app switcher, SN is kicked back in the app selection (in locked state)
4. While the app switcher is still open, don't switch to another app, but reuse SN
5. The SN biometric scan screen is opened, but biometric scan (face id) is not triggered automatilcy
6. You must trigger the biometric scan yourself and press 'submit'

Expected behavior
Biometric scan should triggered automaticly everytime when the SN biometric scan screen is opened for authentication. I'm not sure this behavior is intended, but everytime the biometric scan screen is opened in other situations, the scan is starting automaticly, execpt this case.
