I see in revisions screen in backend ACF fields works well (every time).
And I see in database only information ACF code has to go after are:

– Table wp_postmeta
– meta_id
– post_id
– meta_key
– meta_value

Nothing more.

How on earth ACF code know what is real meta value, and what is revision !!??

OK, I see now. Code knows it by Post ID column (post_id). It is “inherit”, and post type “revision”.
Rest is date of course.
