But you’re creating extra stress on the situation. If you expect it at 2am tomorrow and it appears at 4pm today, that’s a nice bonus. If you expect it at 4pm today and it comes at 2am tomorrow, that is going to cause the stress.
Monzo could take the function away, there’s a delay to the payment, it changes, it’s done another way and suddenly the 4pm option is gone.
And there’s a huge disclaimer on the page that Monzo may remove this feature at any time without notice. I’d hate for anyone to get into financial trouble because they’ve expected it to arrive early - then it doesn’t.
