Hi @Pierre-Michel_Ruel and thanks for following-up. We’re working on launching a major update for My tasks which will allow you to create your own sections instead of using Today/Upcoming/Later. This is why we have removed Today/Upcoming/Later from the Search criteria.
If you haven’t yet, I would recommend upvoting Sort and filter project by multiple fields (Due date and assignee for example) and comment on that thread this is something you’d like to see in My Tasks too. As I’ve mentioned just above, we’re launching a major My Tasks update in the coming weeks (keep an eye on the announcements category for more info on this topic); this new update won’t allow you sort your My tasks by Project and Due date, but it will certainly help make My Tasks more flexible and hopefully help fix your reports!
