Reminds me of that app in which I had to pay something, but if I left the app while doing the transaction (for example, to validate the transaction with my bank app for 2FA) it would cancel the transaction. I literally couldn’t pay without either using two devices or an alternate 2FA method (where the bank would send me a code by SMS - this worked because the SMS would trigger a notificztion from which I could read the code without leaving my app.)
