Not receiving any replies from support (or even getting the auto reply that my tickets have been going through), so I’m going to repost here.
I made a Custom post type with CPT UI (and another through the native wordpress function). Then made a field group in ACF. It doesn’t matter where I set the location of the field group, the fields are not appearing in any of the post editors, even when I set it to the standard post type.
This seems to be a really basic question that has come up previously, but the responses in the other forum answers are set to private.
