Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
parent connection search is broken - if the parent is already in unit an admin can go to roster > Connection Manager > find right square and add A Connection > then go to Scout > Connection > make that connection a parent by clicking the parent checkbox
