Hi,
I received yesterday the new joint card with the new design and added it to apple pay on both the iPhone and the apple watch. The payments through the iPhone are working correctly but when I try to pay using my apple watch the card machine replies with: “card not supported”. The other cards on the apple watch are working correctly and I also tried to delete and add the card back but with the same result.
I had to remove all the cards from my apple watch and iPhone and add them back again. I’ll keep trying in the next few days if the issue is actually solved.
