I cannot add any cards to Apple Pay. I get a message that says "Could Not Add Card: Try again later or contact your card issuer for more information."
I have tried with American Express, Mastercard, and Visa with same result, so I don't think card issuer is the issue.
I did get e-mails from all of the above listed cards notifying me that the cards previously associated with iOS 8.4 had been deleted from my device, so it would at least appear that the cards are not somehow locked in the phone on the old setting. But I'm unable to add them back in.
Any ideas?
