Hi there :)
So I am using the google shopping app through shopify however i am currently getting a message on google merchant center stating Limited performance due to missing identifiers (gtin, mpn, brand). My products are custom made and i have set them as custom made in shopifys app however i spoke to google and they said that my identifier states that it exists and says yes next to it, where as it needs to say no or false, so this needs to be changed, however google said i need to do this in shopify ?
anybody have any ideas how to change the identifier so that it states false please ?
i have already made sure all my products in the google field are set to custom.
For custom products you must remove the values, brand, mpn and grin and set identifier exists to no.
You can use feed rules in Google Merchant Center to set it to false and to clear brand, mpn and gtin.

This post is two weeks old, but this answer might help someone else.
Here's a work around that worked for me. Follow the instructions to add a supplemental feed in Google Merchant Center. Cell A1, the uppermost left header in your Google Sheet, should read "id" and the rows beneath should be the product IDs from "view examples" in Google Merchant Center warning (I just fixed mine and am going off of memory). The column header to the right of "id," B1, should read "identifier_exists." All of the rows beneath it with cells adjacent to your product IDs should read "no." Have Google Merchant Center fetch that file, wait a few minutes and that warning should go away. Hope that helps.
