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.
The Scouting app is an app for Scouts and their parents. It uses the Scoutbook database, but is a separate app.
MyScouting app is basically what you log in at my.scouting.org. I think unit Key 3 and district Key 3 can all add to the calendar. Possibly also Key 3 Delegates, but I am not sure.
My son is going to monthly events, but calendar says 0 % participation. How can we get credit for past participation? We RSVP to events but it is just not showing up on the monthly calendar
