Apple Pay Shipping Address Error

After months of trying everything I can think of, Apple Pay finally worked on the lululemon app! I, too, was having the red "!" error for shipping, even though I've been using the same shipping address successfully for 15 years. What happened was, I was in the dialog box with the red "!" error, then I tapped CARD & BILLING, then selected the other card (I had 2 cards), tapped back and tried/failed again. Back to CARD & BILLING and changed the BILLING ADDRESS, tapped back and tried/failed again. Back again to CARD & BILLING and changed back to the previous CARD, tapped backed, tried again and... IT WORKED! Hopefully, it'll work next time. Good luck!

I had the same issue on my under armor app. But I deleted my card and re added it and it worked after that. Also made sure my cards billing address was up to date.
