Shopify recently introduced pre-order and try-before-you-buy orders. I am verifying how to refund this overdue payment order. Below is my test order, I found that for unpaid items, the amount returned by Shopify’s refund calculation is unexpected, and the refund amount for unpaid items should return 0 to be reasonable. I would like to ask if this is a bug of Shopify or is it expected? This affects our app’s handling of automatic refunds.
