Apple Pay says credit card expiring soon

I use Apple Pay to pay for purchases within an App ( Candy Crush). My credit card is correctly entered into my Wallet ( and has been for years!). The credit card has an expiration date of 11/2024 and up until a few days ago there were no issues and purchases were made and accepted with no issues. Now, when I try to purchase I get a message that the card is soon to expire and I need to update my card. On my iPhone, when I access Media & Purchases ( in settings), View Account, Purchase History there is a message that says " Billing Problem. There is a problem with your current payment method. Update payment method." I have tried to remove the current card, I cannot do so as there is an active subscription tied to it! I have checked with my bank ( tied to the card I'm using) and there are no issues or alerts associated with the card.
