I have a list of tasks in MyTasks all with ‘Due Dates’. I marked a task a while ago that has a due date of the 24th July (it’s now the 26th) but it is still in the ‘Later’ section.
Tasks should automatically promote based on due dates or start dates. I think it’s everything that’s due in the next week promotes from Later to Upcoming, then to Today at midnight before.
Just to check, did you physically mark the task as ‘Later’, or did you drag it into the Later section?
