Log in to Playground on either a Safari or Chrome window. Click on the Billing tab on the left hand side. Click the blue "Enable autopay" button to the right in the Autopay section. You must have a valid payment method on file in order to enable autopay.
Once you've clicked enable, you'll see a summary in the Autopay section that will let you know:
the payment method being used for auto-payments
the frequency of auto-payments and schedule that they will be auto-drafted
the next auto-payment date
To disable autopay, simply click the red "Disable autopay" button in the bottom of this section.
