If you wish to change the payment method for your account, you'll need to wait until your next pledge to a project. Simply enter your new payment details and click "save the card."
To change the payment method for a specific project, navigate to your projects and select "view your pledge." At the bottom of the page, you'll find the option to update your payment method.
If you cannot locate it, it may indicate that you have unsubmitted changes in your order. Click here to revert them:
Once reverted, under the stretch pay view, you'll find your saved payment method with the option to make changes.
