Hi Yes. It’s Santander. I hadn’t tried the two accounts separately, but as you say if one works and the other doesn’t it doesn’t solve the problem. I have now and you’re right the current account works, so there must be an issue with the credit card link.
I’ve lost count of the number of times I’ve removed my cards from the wallet, tried to reset the link, removed and reinstalled the app;etc;etc.
I spoke to Apple Support who tried everything remotely before saying there wasn’t a problem their end. Took hours! Didn’t help the Open Banking link is UK specific, so initially they didn’t understand the issue.
I’ve also spoken to Santander and supplied them with all the screenshots. They went away for a few weeks and rang me yesterday to say they couldn’t see what was wrong at their end. BUT she did say one of her other customers had had the same problem and it had sorted itself out. Unless this was you it does means there is a wider issue. I suggest you ring Santander’s Online and Mobile Banking Support 0330 123 0209. The more of us that report it, the more likely they are to be able to fix it. Narrowing it down to the credit card helps.
Sorry if this appears twice. But my original reply doesn't seem to be visible!
