Is that really the case? That would mean that “Last Modified” is absolutely useless.
Last modified should only change based on an activity. The fact that it has a due date for today should not trigger the Last Modified attribute.
As a PM I want to validate when task have been processed.
To be honest I only noticed today that indeed tasks with a due date of today were set to “last modified” today although no changes were made. I agree this is a bit weird.
And I did have another task where a comment was added to a subtask but it did trigger the “last modified” date of the main task.
I have also found this task with a discussion about what normally impacts the “last modified” and the due date is not mentioned there
A bit weird indeed to be honest. I will do some more testing with tasks.
