I have 2 cards entered into Apple Pay, an Amex which I added first, and a Capital One Mastercard which I entered later. Every time I make a purchase with the Amex (even a swipe transaction or online purchase) I get a notification, almost instantly. With the Mastercard I don't get notifications. I do get them through the Capital One Wallet app, but that's not the same thing. Notifications are turned on for this card.
The Amex is my "default" card in settings. Will it only show notifications of purchases for your default card?
