The storefront delete button will work only for autonomous plan users (paid plan users).
If you try to set up the delete account (unsubscribe) button while using the Ecosystem Plan (free), an error message will appear, and the deletion will not be successful.
If you encounter an error message, please first check whether your plan is the 'Automation Plan (paid)' or higher.
*You can change your plan: Open Delete Me> Settings> Subscription Management.
