If you’d like to update your credit card information or change your payment method from PayPal to a credit card, log into your Subscription Portal and select Edit.
If you signed up through the Google Play Store, the App Store, or if your payment method is set to PayPal, you won’t see an option to edit. Instead, you’ll need to visit the Google Play Store, the App Store, or PayPal to update your payment method directly with them.
