Apple wallet saying incorrect billing address for all cards
Nothing has changed, but suddenly when trying to pay using any of my cards in apple wallet (phone / MAC) it says the billing address is incorrect. Nothing has changed, I haven't moved, address hasn't changed, same old cards, but suddenly none of them work.
The only way I can now pay is through PayPal. I have checked in all the places addresses are stored (Apple ID, wallet, on my Mac) and they are all the correct address (no typos) and haven't changed.
I'm stumped!
Please help as I can't buy anything!
Thanks
