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.
Can be problematic if there is not a globally unique place that the BSA systems sync information into.
Our Council Key3 mentioned issues with helping units do contact tracing back in 2020-21 was hard since when phone#s were not being updated in my.scouting. Either parents not thinking to update contact information when it changes or updating in Scoutbook but doesn’t get synced back to my.scouting.
Understand it will take time. Believe we have others in our unit with various address issues in Scoutbook. Trying to get a complete address list at least from the Scoutbook side, the reports only show the parents address and not the youth address. Our case here was that the activity waiver included the Scouts address(old) not the parents address(current)
