Barcode Identifier Type Missing in Amazon Listings Settings
Please add an "Identifier Type" dropdown to set the barcode type on Amazon Listings.
On a product level, StoreFeeder supports both UPC and EAN barcodes.
For eBay listings, StoreFeeder provides an "Identifier Type" dropdown to select which barcode type is uploaded.
This dropdown is missing for Amazon listings. Instead, StoreFeeder is hardcoded to submit an "EAN" barcode type.
As a result, creating Amazon listings for products that only have a UPC barcode, will create the product with an invalid product identifier.
this has been reported as a "bug" and is in the development queue.
