Why Amazon Auto-authorized when it'a past return window???

@Seller_z0yu129sVnKKP Thanks for that question about the return policy and window.

Manage seller-fulfilled returns

• Amazon's returns policy allows most items to be returned for a refund or replacement within 30 days of the estimated delivery date.
• After you authorize a return request, the buyer has 15 days after the return window closes, allowing for transit time, to return an item.

The return window and 15-day transit time are both based on the estimated delivery date and are not affected by the actual delivery date.
