I shipped an order to a buyer through an APO. It was ordered 1/5/25 and shipped 1/6/25 using Amazon's buy shipping and was shipped within the shipping window. 1/30/25 he messages me to tell me it didn't arrive. I checked, and it was still in transit. I told him to open a A-Z non-receipt claim. He opens an return request. 2/12/25 he messages me that it arrived, but it was too late. He opens another return request. And he wants a pre-paid return label. Amazon always issues a prepaid label to refund at first scan. I told him to use the pre-paid return label that was attached to his first return request and take it to UPS. I wake up to a message this morning stating that he took it the post office (USPS) and that the label is not prepaid. He sent me an image, and it doesn't look like any return label I have ever seen.

Questions:

1. Why didn't Amazon issue a pre-paid label like they always do with return requests?

2. If he files a claim for late delivery, will Amazon honor and pay it with no effect to my ODR?
