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.
@dpaluszek - my first question is are you logging in to the app with the same credentials as scoutbook? On the connection page in scoutbook if you are not an adult leader for you son as well as other family member then save.
I also tried it with the exact username shown in my.scouting (dpaluszek%40gmail.com) and got more of a specific error this time: “Sorry, unable to get user role.”
Did you ever click on your name from your son’s connection page to make sure it showed the same email address? I briefly had a suspicion that there are two different versions of you.
