#Amazon is not updating the changes I made to my listing. I am sure a lot of has faced this problem multiple times during your time as a seller on Amazon. There are actually two different reasons why this happens.
1. Amazon has protected the rights to edit a particular ASIN – This is something they do to an ASIN once you’ve had the listing up for a while and it’s the type of product that are easily hijacked. So amazon puts a bar to all edits (most of the times it’s the title and images) made to a listing unless the ownership of the ASIN is proven to them.
2. You have product that is listed in parent child model – When you have a product that has multiple variations of colors and/or sizes you are required to list them on Amazon using Parent-Child method.
With the parent child listing there are 2 methods that amazon uses
a. DPM – In this model, whatever details you put in as Title, Bullet Points, Description into the Parent ASIN will be shown on the public page of every child under that parent.
b. DCM – In this model, whatever details you put in as Title, Bullet Points, Description into each Child ASIN it will be shown on the public page of every respective Child ASIN individually and it won’t matter what is written on the parent listing.
Unfortunately you won’t get to choose which model is used for your ASIN and they have different modes set for different categories.
Based on our experience dealing with our different clients we have observed that Amazon uses the DPM method on Apparel, Cellphone Accessories, Supplements and Leather Accessories.
If you are unsure then you can reach out to seller support and find out which model is used for your product category. But there is good chance that not all seller support agent might be aware of this. So if you see them confused then go ahead and try editing your parent and see which one sticks.
Lastly here is an actual reply we got from amazon support for a similar issue with one of our clients.
