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

Hey, Is there a way to make an existing tester a sandbox tester? I am having to signout of my phone everytime I test In-app-purchasing. You have to re-add your credit card etc. It's a real pain. Thanks!
