The UPC is not included when you download your active listings via the
new Seller Hub Reports. This is a very important feature for restocking,
so if there is no way to do it, this is a big problem.
It's missing all the predefined spefics for that particular category.
You can add new ones, but you can't see or edit existing ones. Started
happening around 4PM eastern on Oct. 23.
I called eBay and they said this is a known issue since August and that
the estimated fix date is 90 days from that (November). I really hope it
doesn't take this long.
