Instead, you can create a new task or just reschedule your existing task by adding a new recurring due date that starts at your previous instance. You can add the following to a task: notes, URLS, to-do list, tags set priority and deadline create reminders move to another project or section create a duplicate, mark it as completed, or delete it. Note that you won't be able to undo the recurring task once the pop up message disappears. You can't undo any previous occurrence of the task. For example, if you have a task due everyday, and you complete it today, you can only undo today's task. It’s not possible to undo any previous occurrence of the task. The completion of recurring tasks can only be undone right after the occurrence has been completed, by clicking “ undo” in the popup (web, Windows, macOS) or by tapping the undo popup (iOS, Android) which appears at the bottom of your screen. Inside your projects youll be able to view all of the projects tasks that have been completed and removed from your active task list.
