On phone/hold with Apple re: American Express notifying me the card is removed from Apple Watch, no longer will use my AE card via Apple Pay because, AE rep says, "Apple changed something yesterday." Apparently still fine on iPhone. The AE email came just before midnight Tuesday. Saw this a.m. and called AE. They confirmed as stated above "Apple did something yesterday." Still on hold with Apple. off hold with Apple, awaiting callback, rep knows nothing but is checking back when I know something. maybe reload issue after 1.0.1 update. edit: Rep called back to confirm I wasn't using an AE Corporate Platinum (I wish!). Nope, just an average rewards card totally accepted before May 27 (I've had the watch since 4/24.) Awaiting another callback.
