Hi @Alain_Iskandar- I’m sorry for your frustration and confusion, and I hope I can help with some information about the logic of My Tasks.
The default sorting option in My Tasks is the “Incomplete Tasks” view which utilizes the Priority sections of “Today”, “Upcoming”, and “Later” to prioritize what you want to do today and this week. If you change the view to sort by Due Date, you will then see all of the items that have due dates at the top in chronological order, and then under that, you will see the items without due dates within the priority section they are in (those marked for Today, Upcoming, or Later). If you were to switch the View back to sort by Incomplete, you would see those tasks without due dates in your Today section.
Therefore, if you want to utilize the “Tasks by Due Date” view, I would recommend putting dates on everything you want to see in the top ordering. Otherwise, I would recommend utilizing the Incomplete Tasks view with the Priority sections to get a good list of everything due today each morning. You can see more about the priority sections here..
Let me know if you have other questions on this, and hopefully others can chime in with how they use their My Tasks.
