Hi @Berger_Marc , welcome to the forum.
If you open a task and scroll to the bottom and checkout the tab ‘All activity’ can you see a with the name of a rule that is assigning the task to you?
the rule (i can’t show you screenshot) says : when due date is coming (Tasks to finish today) then move to section “To do today”)
As you can see, the rule is about move my tasks on antoher section in the “my tasks” list … but not to assign them. And it should only concern my tasks.
i just check and i can’t add anything like “check if the ask is allowed to me” before the move.
that looks like all the tasks in asana which have the due date to today will be assigned to me ?
