Cannot add card to my wallet
So, my wife is having trouble adding a card to her apple wallet. I can add it to my phone’s wallet no problem. This issue has persisted from her iPhone 11, to her iPhone 14 pro, and now to her iPhone 16 pro, all with the same issue, “invalid card”. We have contacted apple and only been told that it is an issue with the bank, which clearly isn’t the case if i can add it on my phone. We do have our own apple ID, so that’s all i can imagine is left that can be the issue. Any way to fix this? Sorry, put the wrong device on the tag, it’s on ios18 with an iPhone 16 pro.
