Where can I see previous issues of a recurring task?

In the Task log, you can view all previous instances of a recurring task by filtering by the task title and setting the deadline filter to "All time."

These past instances will be labeled as "Expired" in the "Status" column.

A task is marked "Expired" when a new instance of that recurring task has been issued.

Expired tasks are included by default in the Task log. To exclude them, use the "Advanced filter" options, set the "Expired" filter to "No," and click "Apply filters." To view only expired tasks, set the filter to "Yes."
