I can't set up either of our Discover cards. I can get through the process up to the last step, but it says it was unable to add the card. I called Discover and they said they are aware of reports, and it may be Watch OS2 related. I'm using an iPhone 5S so that may be part of the issue. iOS9 and WatchOS2. Anyone get Discover to work with Apple Pay? What devices and OS? Did you have any issues and if so how did you work around them?
