I have Woo commerce based E - Commerce Store
I am using "CTX Feed" Paid Plugin to generate and mange Google merchant product feed
My product Feed is showing 2 error which I am trying to resolve
1. Incorrect value [identifier exists] -"This item has an internationally recognized, unique identifier. Submit a valid GTIN, and either set this value to true or remove this value."
2. Invalid value [gtin] -"Use a globally valid UPC"
Steps Taken --
1. I added "GTIN" filed with every product and passes GTIN value to products for whom I found GTIN.
2. I Added "GTIN Identifier Exist" filed with every product and passes True and False accordingly.
But Still I am getting both error
Looking for freelancer who can help me to resolve both issue and can help me with list of GTIN code as well.
