What I did:
Created a saved search: Tag name contains due( Next Four Weeks)
Only notes with due in next four weeks that also have the On the Agenda” flag (orange dot) set appear
What I expected:
I don’t understand the dependency on the On The Agenda flag?
Things that might be helpful to know
Agenda v7 macOS
(and thanks too to @Pat_Maddox for his interview on the iPadPros podcast introducing me to these creative ways of using Agenda)
