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.
I have an interesting dilemma. In July our troop got a new scoutmaster. When I view the troop roster the new scoutmaster is listed correctly. When the new scoutmaster went in to sign a new blue card for a scout he was not able to. Upon looking at the scout’s connection the new scoutmaster was not listed as scoutmaster under his connections he was only listed as an adult leader. The previous scoutmaster was listed as the scoutmaster under all individual scout connections.
By default the Scoutmaster is a Unit Admin. Units can change their unit admins based on unit needs. I know of units where some admins have asked for the admin role to be removed because they are afraid they may mess something up.
