Currently, there is no way to stack sorting so that when filtering by Project, the tasks can be arranged chronologically by due date within those projects / sections. This option is only available when looking at other people’s task lists, and by manually dragging my own tasks into the proper order once filtered.
I reached out to support and this is the response I received: “When you view someone else’s My Tasks it will order them neatly and cleanly by due date when sorting by project because you do not have access to their My Tasks list. If you had been invited to edit the other users My Tasks you will see it is not organized if you sort by Project.”
Doesn’t make a whole lot of sense to me why I wouldn’t be able to automatically organize tasks in each sub-section, since it seems like an obvious feature to order tasks under each Project by when they are due. I would love to see the “neat and clean by due date” as an option for my own tasks, and not just for others on my team.
