All of the Camping I had recorded in ScoutBook prior to September 2020 has disappeared with the conversion to Internet Advancement tracking for Activities. Where can I recover the data I had previously entered?
Where are you looking and not seeing it? When you look at IA, make sure you have the filter set to include individual events.
I tried several places…ran an activity/camping report for all scouts and all 2020 dates and also looked at individual scouts I know attended.
