I have created a field group and assigned it to the user backend profile page (location: user form). These fields show below the password button, at the very end. Is there any way to move these fields up, preferably at the very top – as first?
Also, can this be done depending on the role of the user whose profile page is open?
No. ACF uses the hooks provided by WP to insert the new fields and they are inserted in the only place that WP makes available.
