I created a SharePoint 2013 Designer Workflow. And in assign task I configured Overdue emails daily.
But when assign task triggers it sends TASK CREATION email but overdue mail is not getting triggered.
Please help resolving this issue.
This may be the silly answer, but I noticed that the Due Date field isn't set in your screenshot - in my experience it has to be set there (it can't be added later) to trigger the overdue emails. Usually what I do is use the action "Add time to date" to add two weeks or whatever to [Today] and then use the resulting variable to populate that Due Date field.
