That was discontinued in June due to the BSA rolling out ScoutBook. Take a look at the updates page in TroopTrack for the latest and instructions. It is clunky but I think TT is working to make it better.
BSA IA 2.0
With the recent updates the BSA made to their Internet Advancement systems, TroopTrack’s TurboNet no longer connects as it previously did. We have made progress with TroopTrack’s integration with the BSA’s new Internet Advancement updates (IA 2.0/Scoutbook). TroopTrack has created a way for us to upload rank advancements TO council. You can see a video on how to do this here: Internet Advancement 2.0. TroopTrack is still in the process of adding a feature to synchronize FROM council. TroopTrack is confident we will have a solution but it is slower to release due to the lack of assistance from the BSA.
