+1 to this issue, I am curently on WP 4.7.2.
John, does your installation say this plugin “is compatible according to the author”, or are you just saying it seems compatible according to you, as a user?
I see it at this path:
/wp-admin/plugin-install.php?tab=plugin-information&plugin=advanced-custom-fields-pro
