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.
We’ve recently added a girls Troop. After we updated all of our events to include both Troops, SB is sending two event notifications - one with the correct time (ET) and one an hour back (CT).
I see this has been an issue in the past that may need to be addressed by developers.
@GaryFeutz Anytime I see these I think they would a great Assistant/Addin feature. So when it does a roster scan it could check to see if a time zone is set and flags it if none is set.
