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.
When trying to create a meeting series with joined troops (for example T829 and T829G, trying to create the monthly Committee Meeting). I have discovered the following issues -
when selecting multiple calendars, after selection it shows Troop 829 twice (not Troop 829 and Troop 829G). This issue happens whether it is a single meeting or a series).
after creating the series with both troops, It only shows up in Troop 829’s (the Boy troop) calendar.
