I created several new products and the feed at the Google Merchant Center updated; but now the few products that had been approved have now been dropped since they are not in the feed anymore and still all of the t-shirts, sweatshirts and hoodies are still disapproved for Google Shopping Ads since they don’t have size attributes.
I would like to suggest that there be an option to build a feed, based on category.
This would allow for the addition of sizes without having a huge feed that would end up being to large for GMC to crawl and would let us advertise t-shirts, sweatshirts and hoodies in GSA.
