Payments are managed directly by the app stores (Google Play & the Apple App Store). If you are having difficulty with a payment method, or if you would like to use a different payment method, please check your App Store or Play Store account and update your payment method there.  If you are redeeming points from a reward system, you may need to double check that your balance covers sales tax.

If you connected a credit card to your account, that is used for the merchant platform ONLY and does not have any effect on in-app purchases.
