I’m having an problem where Google Merchant Centre flags an issue that the [size] field is empty when an item is set up with multiple variants for the different sizes.
I’ve tried adding S/M/L as a size (the sizes that the variants cover) to the parent item so that the field is not empty, but then that flags as Too Many Values.
Has anyone else had this issue? Any help would be greatly appreciated.
Normally you should add a variant with the variant option size, then Google can pull this data.
You could also edit the data manually in Google merchant center: https://www.youtube.com/watch?v=XNwg9-4-eGg
You could also use a supplement feed: https://support.google.com/merchants/answer/7439058?hl=en
Or use a an app where you can map all attributes such as: https://apps.shopify.com/multiple-google-shopping-feeds
