If you have a current subscription paid using a credit card, you can now update the card details via the customer portal. (Provided by Stripe.com, our payment processor.)
When viewing your "My Subscriptions" page, if a current subscription is active (shown in green), then you can use the "Update" to change your payment details and email address.
Note : This is not relevant to PayPal, Apple Pay or Google orders, where you should update your orders within those services themselves and no customer portal in necessary.
To cancel, please continue to use the existing link shown against each subscription.
