Samsung pay is behaving rather strangely for me. I have both a US Bank Card and an American Express Card registered with Samsung pay. When I use Samsung pay with my US Bank card, the transactions do not show up in Samsung Pay. When I use my physical American Express Card (not using Samsung pay) the transactions DO show up in Samsung Pay. Anyone have any clue what is going on? The amex receipts show the last four digits of my physical card, not the four digits assigned by Samsung Pay.
