Hi,
Looks like google started implementing the GTIN requirement, see
https://support.google.com/merchants/answer/6352134?hl=en
does anyone have experience implementing this in Firetanks feed software, currently I am using brand = manufacturer and MPN = sku in standard x-cart settings.
Standard x-cart (I am using 4.7.3) does not include a GTIN or sku, if I am correct.
Any easy solutions?
