All payment options, including Express Pay, are working but there's an odd aspect with using Express Pay with Apple Pay on a Mac as opposed to an iPhone: on the phone I pay and get to the receipt page with the option to continue shopping as expected, on the Mac I get a pay for my order page. Note: My initial Apple Pay was successfully processed (got the email and logged into to AmEx to confirm I was charged) but an identical order appears on screen. I tried completing that order to see if it would accept it, it did as a new order (also emailed and charged successfully). Obviously on a Mac a customer should get routed to the same place as on an iPhone.
Fairly certain this isn't something I can fix on my end, but if so, let me know. Thanks!
