worst app ever! not intuitive at all! much better Revolut app for handling moneys. In my case I did a payment at the time with PayPal but for some reason it didn't get money from the associated card. They tried to call me without even sending a notification on the App, there was no mention about this missing payment! The problem was that it was associated with an old phone number and I received the call by pure luck! But I'd first notify via app and THEN try to call.
