I have the cards in my new iPhone 7, but when I try to add them to the watch, using the app, I just get a spinning wheel, and the card doesn't transfer. I tried doing a hard reset on the phone and I power cycled the watch, without results. I want to add that this is the second Apple Watch I have, so I take care to be sure that I am selecting the right watch when I start the process. Any suggestions? Thank you!
