Products Feed Specification changes
the alert for google_product_category was given here:
i was able to insert an item using that value.
however, where was that error message seen exactly?
that does not look to be a google-merchant-center error.
if that error is from a third-party implementation
of google's api -- such as magento, xcart, etc.,
then the third-party or third-party forums would
need to be contacted for support.
