To confirm … you uploading with a excel template and had “Update” selected?
It would seem that you were trying to create the child ASINs which already exists to receive that message or the Amazon system was glitching at the time of submission
the children seemed to have updated fine in the end looking at their pages… actually, wait… can this be it?
I had the old List Price in the List Price column of the Pink Offer section, but had my new price (trying discounted for volume) in the Brown Offer section for the markets, wher ethe Your Price USD was lower than the List Price under Offer.
That my likely issue?
Everything updated on the listing but the old list price remained.
alright, let me make an alternate partial spreadsheet (trying to keep all my completed flat files for future updates). I originally created all my listings the online dashboard way but discovered you were SOL if any issues and listing pulls in updating that way once they are locked.
