Well, I heard back from SS and I don’t understand a word of what they said!
"We understand your concern is that you are unable to successfully list the SKUs in your Inventory.
We have reviewed the SKUs provided by you and see that they failed to list in your Inventory as the product ID provided for the listings were invalid.
Please know that as per the new update you will not be able to list the ASINs with product ID as ASINs, the listing must have a valid product ID provided during adding the product to created successfully.
I kindly request you to please list the ASINs with a valid product ID to fix the issue."
I have no idea what they are talking about!! I had a chat with someone from SS who said that the ISBN is the product ID. Of course, I was listing the books according to the ISBN, and the page is Amazon’s, not mine. After I briefly explained the whole thing again she then suggested I clear my cache and cookies. I felt she had zero grasp of the issue and so gave up and emailed SS back.
For goodness sake… I thought I was getting somewhere yesterday.
