I'm trying to test payments on an iOS app. I have a sandbox account and its worked previously. When I try and add a test credit card I get the error "Your Issuer Does Not Yet Offer Support For This Card" I'm using the cards here https://developer.apple.com/apple-pay/sandbox-testing/"
What I have tried:
- Checking my Region is the UK
- Checking the card details
- Tried several cards
- Tried signing out of my iCloud completely
I'm testing on an iPhone 12 mini using iOS 16.5.1
