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 have switched from using Google Calendar for our Troop to using Scoutbook. It appears the ics feed from Scoutbook does not include event reminders. So parents that add the troop calendar to their phone are not getting popus before events, even though we have a reminder set in Scoutbook.
Also, could be we get reminders for 30 minutes as an option. 1 hour seems too far from some events such as scout meetings.
I made a ticket - but doing some research I am not sure how stable valarms are across the OS’s - It seems iOS might have disabled them - and Only one alarm is 100% reliable it seems. IT will have to research if they proceed.
