@JessicaKlopp, Troopmaster does still have the ability to generate an upload file for Internet Advancement, just as it did 3 months ago. Personally, I think the new upload file processed smoother, and with fewer steps than Internet Advancement 1.0.
You are absolutely correct that Troopmaster is an added expense, but for a large Troop not that much per Scout. Although some suggestions are included in future updates, some will take a while to be implemented, while other Troopmaster features BSA has implied will never be made available.
Once size, or product does not fit all. As I indicated in my earlier reply, units need to go in with their eyes open and make the best decision for them. Some will lose little functionality compared to how they use their current unit management software. For others, they will lose tracking capabilities, and granularity, that they depend on for their Scouts, and which is near non-existent for leaders.
