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’m a key 3 (cubmaster) and also a den leader. My scouts are listed in the Bear Den , but when I click on an individual scout, it says they are in the wolf den.
Also when I try to add advancement in Scoutbook Plus, it lists bear requirements as disabled (see screenshot). I was able to add some requirements somehow a few weeks ago through the unit quick entry, but Bear adventures are listed as past approved adventures and wolf adventures are listed as current.
