Hi Mikemikeford,

If you're having trouble updating your payment method, we've got a few suggestions to start with:

Verify that you're following these steps:

If you need to change or update your Apple ID payment method - Apple Support

If so, contact your financial institution to verify that everything is good on their end and that you have the correct information.

Then, this page has the accepted payment methods for each country/region:

Payment methods that you can use with your Apple ID - Apple Support

Double check that your payment method is still accepted.

All the best.
