Hi, I have the same problem, but i don’t use a shop page, i use my catalog only to tag my products to my Instagram and FB posts. I have 59 products on my WooCommerce. When I sync my products on Facebook, I have two alerts on 39 products with missing fields “variant_value” and “variant_label”. Facebook said that 59 products updated. But I have only 20 products on my data flow.
I am worry about delete and recreate my catalog because i think that will remove all the products tags on my posts on Facebook and Instagram.
Ho can I fix that?
