How to update payment information?

1. Login to the customer portal. (Not sure how to do this? To find this link, the link is normally sent in the Subscription Confirmation email when you begin a subscription and the Upcoming Order email)
2. Click the Payment Methods
3. Expand the payment method to be adjusted.
4. Click edit.
5. Click Send update email on the slider.

If you used PayPal as your payment gateway, you can edit the payment method in your PayPal settings. Otherwise, you need to cancel the subscription and start a new subscription via checkout.
