I opened my bank's mobile app to do an e-transfer. When I hit "send" on the transfer, it demanded that I verify my ID for security reasons, with a bunch of steps.
Frustrated, I hit the back button intending to abort and switch to laptop... But that took me back to the transfer confirmation screen, so just for fun I hit "send" again... and the transfer went through just fine without the security verification.
From this I'm inferring two things: nobody tested the failure transitions in the workflow, and so the app merely records that the verification flow was previously _entered_, rather than completed successfully. And, possibly, the bank's android devs are too young to remember that there's an OS-level back button that's not in the default UX any more, but you can turn it back on in settings.
