Global attribute for WooCommerce variations
I have a situation where we have lot of products sharing similar variation type. i.e. "size".
When importing products from square, the products are created with custom variations, specific for each products in woocommerce.
It means that it's impossible to filter those products by the global attributes via the widget layered navigation attributes.
The only option is to manage attributes and it's stock via WooCommerce.
We loose the advantage to sync stock with Square in this case. There is no options to filter by attributes.
