Wallet won't let me add any credit cards

Here is a screen shot of the pop-up.

Wallet won't even let me get started on adding a card, so there is no card issuer to contact. Regardless of anything I have tried, the pop-up always occurs. I wish there was an issuer I could contact. When I get some time, I will call Apple.

Thanks for your input.

In an attempt to solve another issue, I did a factory restore and used the latest backup to restore. I added the card on file with Apple when prompted during setup and everything appears to be working as advertised. Have added several cards with no problem.
