[iOS] Keyboard doesn’t appear when asked for pin (and touchId bailout fails to work)

Issue:
Keyboard doesn’t appear when asked for pin (and touchId bailout fails to work)

Notes:
The issue is no longer apparent after taking the time to write this bug report so some remote dependency might have been the culprit. (Thanks for fixing it if that was the case!)

Details to reproduce:
Given I’ll be required to re-enter a card pin on next use
When the pin confirmation blocking modal appears
Then I expect to see the iOS keyboard or another input method
But I have no way to input the PIN numbers
And I see a permanent data loading indicator on the top left of the screen (screenshot 1)

(…)
When I use the touchID option on the top right
Then I expect to be able to use touchId to unlock the app
But the screen is blank
And I can see a permanent data loading indicator (screenshot 2)

OS:
iOS 13.3.1
Device:
iPhone 8 Plus

Hi - I have exactly this problem now. Do you have any idea what causes it?
