How does subscription handling work with withdrawal?

Upon filing a withdrawal declaration for an order containing a WooCommerce subscription: (1) all associated subscriptions with active and on-hold status are cancelled immediately, (2) the proportional amount for the unused portion of the current billing period is calculated in accordance with Article 9(2)(b)(iii) and recorded in the order meta, (3) a cancellation note is added to the subscription and parent order, (4) the customer sees a confirmation notice in My Account. The operator sees the proration in the refund preview and can accept or modify it before clicking “Approve”.
