I have a bunch of fields inside a User Field Group that I want to use with a CPT.
I tried to find any "move" button.
Tried to create a new Post Field Group and "choose from previously created fields", but it does not show any user fields.
Last chance is to create them again but for Posts. Any ideas?
Because WordPress stores custom fields for posts ("post meta") and users ("user meta") in separate database tables, they are handled separately by Toolset, too, and you cannot re-use post custom fields as user custom fields or vice versa.
I'm afraid you will have to create new post fields as required.
