Can't add debit card to Apple Watch
I have discovered over the last couple of days that my Apple Watch isn't working for Apple Pay. I have deleted the card from my iPhone 6 and re-added it with no problems but when I attempt to add the same card to my Apple Watch, it fails with the pop-up error of Card Not Added - Contact your card issuer for more information. Add card later or Try Again. I'm with Lloyds bank in the UK and don't understand why it would seem to work on the iPhone but not the Watch.
iPhone 6, iOS 9.3.3
