So...in my previous posts I've been asking for how to display fields of an intermediary that is INVISIBLE.
Apparently one can't.
"To be able to display information from an intermediary post type, you must make it visible in the WordPress admin menu. The option to set this is available in the wizard for creating post relationships." https://toolset.com/documentation/post-relationships/how-to-display-related-posts-with-toolset/
The reason I was inquiring about displaying fields when intermediary is invisible is 'cause when I make it visible the query is EXTREMELY slow.
