Hi @k83uhse6v
To use Facebook for Woocommerce on a WordPress Network installation you would need to install and activate the Facebook for Woocommerce plugin on each individual/separate sub-site initiated on the WordPress network installation.
You can then connect Facebook for Woocommerce to each Facebook business account which you’d like to use for each network website.
As long as the multisite site has its own dedicated domain name mapped (not based on folder setup), the plugin should work.
