iPhone App Store verification on iOS 13

[groovyf]

Currently running iOS 13 public beta 2 on iPhone X, and I've noticed that when I attempt to download a new app from the App Store, I'm getting a prompt "Verification Required" - "Before you can make purchases, you must go to Settings > iTunes and App store > Apple ID and verify your payment information".
Tapping "Continue" on the message takes me to the Manage Payments settings. My current debit/credit card is already listed with "Apple Pay" in brackets.
If I try to manually add my card, it tells me it's already been added.
I'm guessing it wants me to verify my card number, CVC code, but as it's been added via the Wallet App, I can't do that.
Is anyone else experiencing this?

Thanks in advance?

I've removed the card from payment methods, as well as from the Wallet. I re-added my card to Apple Pay and it's now not listed as a "payment method". Manually adding my card details has solved the issue.
Can anyone confirm whether an Apple Wallet added card appears in their "Payment Methods" settings with "Apple Pay" in brackets...

[Edit: Checking Apple's page: https://support.apple.com/en-gb/HT202631#europerussiacentralasia regarding Payment Methods, it doesn't actually list "Apple Pay" for the UK. Maybe a bug in the iOS 13 beta altered my payment method from "Visa" to "Apple Pay".
