How to cancel your customers' memberships
To cancel an individual customer's membership, simply head to your Audience dashboard, search for their name or email, and click Cancel Subscription.
However, as a creator, you also have the following options:
How to prevent new customers from subscribing
If you're looking to keep all your existing subscribers and not accept any new subscribers, simply Unpublish the product. Any new customers will not be able to buy or find the product, while existing customers will continue to be charged and have access to their files.
How to delete a membership product
To cancel a membership for all customers, go to your Products dashboard and hover over the product you'd like to delete. Click the 'x' next to the product to delete it.
When building your product, you can set your membership to terminate after a set number of months.
