Apple ID and Payment/Subscription Issue

On my iPhone 14 I had downloaded a subscription based app whereby I received the receipt. I have now recently purchased an iPhone 17 Pro and I have tried to download WhatsApp on this phone however, I was unable to because it states that my subscription based app that I have recently unsubscribed to has unpaid payments now every time I want to update the credit card or edit it. It’s either says that this card is on file or I cannot edit or add another card.

What shall I do?
