What I did: Set “All Day Reminders By Default” in Preferences.
What happened: Reminders still assign a time to them, unless I use \reminder, doesn’t matter using Mac or iOS
What I expected: No matter how I created a reminder inside Agenda, it would default to “All Day”
Things that might be helpful to know (Agenda version, OS and model, etc): Agenda Version 11.0.1 (150) - Mac App Store, 10.15.7 Mac OS, current OS on iOS and current app on iOS
