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 am a Den Leader. For some reason I can no longer enter any advancement, awards, nor adventures for any Wolf Scout except my son.
I used to have “Full Control” permissions, and now the permission level states “View Advancement” and “View Profile”. I contacted my local Cubmaster and Pack leaders with this issue last week, and they’re unable to identify or correct the problem
@Stephen_Hornak was getting at what’s shown when you log in to my.scouting.org. Sometimes there’s a mismatch between the registered positions at my.scouting.org and the listed positions at scoutbook.scouting.org. That mismatch can be one cause of the issues that you raised.
Try this. From the pack roster page, click your name, click your current den admin position. Make sure the position approved box is checked. Click update.
