Q&A: If I'm overdue on a yearly reoccurring Task by 11 months - what happens to my new Task when it is reassigned a month before the deadline?

You will get a new Task when the recurring date arrives.
Your previous overdue Task is then marked as ‘expired’.
Once a Task has been marked as expired, it does not mark as complete automatically.
So, if you complete the Task, only the active (most recent) recurrence will be marked as complete.
