I wonder how much of these problems we've seen are due to parents checking out on extracurricular activities during/after COVID? We had problems just as COVID was hitting, with the leadership turning over, and that group of 5th graders not continuing with Scouting - which would be the 14-15 year-olds.
In our instance, with the Pack and some of the others I've seen, I think the current 5th graders were hit hard because that was the group that would have just been getting into Scouting as little kids before other activities could take root (baseball, soccer, etc.). We tried to navigate COVID as best we could, and rebuilt our groups successfully afterward (bigger and better than pre-COVID) and both our Pack and the Troop we feed into are doing fine, but we also have some solid leadership.
I find it interesting that all of the sudden, the national council is pushing everybody to crossover their AOL Scouts to the Troops in December (or earlier if we can), and to start having our AOL Scouts camping with the Troops starting last month. I know they were testing stuff last year, and I know they started putting out the information earlier this year about crossing over early, but it seems like things accelerated recently. My guess is they are trying to get the incoming middle-schoolers fully into their Troops before middle-school activities take over. And I don't have a problem with that at all - I felt like Webelos II was just us spinning our wheels and shadowing the Troop anyways, since Boy Scouts were having to run most of the requirements for them.
