You haven't hit the right (wrong?) use case yet. I had to wire some money to an overseas resort for my honeymoon. I hit the currency control restrictions. Except I only learned that because I work for the same bank I have my accounts in, so I went to the gal in charge of the payment processing system, she told me the status, then I called the right person in the currency control unit who told me I had to send a freeform message via the app with a copy of the invoice as an attachment. What did the app itself (or the web client) tell me? Nothing, "payment processing is in progress".
