I have the pro version. Upon uploading a products via the Product Feed, I get a couple of errors from Google –
1) (CRITICAL) Insufficient product identifiers: Missing two out of three attributes [GTIN, brand, mpn]
We have all custom products. It seems that if the MPN – Enable Box is UN-Checked, you should include this in each product-
2) (CRITICAL) Missing ‘shipping weight’ attribute.
Because we use FedEX Ship Setting that required weight, this attribute is required. Seems easy enough to put the
<g:shipping_weight>3 kg</g:shipping_weight> attribute. Probably would not hurt to add these –
