When a subscription is manually cancelled by the customer, its status is not usually transitioned to Cancelled immediately. If the subscription has a pre-paid term that has not been provided yet, the subscription will be assigned the Pending Cancellation status.

During this time, the user associated with the subscription will continue to have the subscriber role, and may be given special access by other extensions, like WooCommerce Memberships.

When the pre-paid term ends, the subscription’s status will be transitioned to Cancelled."
