add card to apple pay - UK banks

Less of a question - more of information. I received a replacement credit card from a UK bank and tried to add to Apple Pay - had to delete the old card first obviously. however - still got the messages around "Card not added" and "Contact issuer".

The point is that trying to add the card via the Apple Pay wallet app may not work. Some card issuers require you to add it via their own banking app. In my case I had to go to the NatWest app and find the card account - then there is a symbol to press to add the card to apple pay with the bank's own security processes.
