I have a parent theme with its own custom fields for a top level organization site, and a child theme with its own custom fields applied across a Multisite Network.
I’m moving all ACF declarations from the admin UI to functions.php with the PHP export utilizing acf_add_local_field_group. But now these fields are being applied to the child sites, too.
What would be the best way to migrate these fields to functions.php without them interfering with each other? Can they be declared for specific blog IDs only? Or should I give up on the parent theme idea?
