Due to a licensing issue between American Express and Mollie, our payment provider, it is not possible to use AMEX cards for autopayments at the moment. We are investigating to see if any solution to that issue is in sight, but that might take a while.

Meanwhile you have the following options:

• Recreate the autopayment with a different (non-AMEX) card
• Make single payments with your AMEX card through PayPal
• Make payments via the new bank payment option.
