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.
My pack is new to using scoutbook and each time anyone (Cubmaster, admin, parent) tries to update advancements it redirects us back to our dashboard.
Example: went to a scout working on Webelos rank, attempted to click on First Responder to mark off completed achievements and it redirects me before it even opens to First Responder.
