Remove a recurring Todo

If you have created the recurring Todo inside NotePlan, then you have to delete each entry manually in NotePlan or delete the text files from the iCloud Drive (they might only contain the recurring todo).

That's because NotePlan saves everything as plain text (except the calendar and reminder events) in your iCloud Drive. There is no database tracking each entry. Recurring Todos in NotePlan are very simple and limited in functionality. If you need more recurring features it is better to add a recurring event into your Reminders or Calendar app. It will be synced into NotePlan.
