Overdue tasks not showing up in daily email

There’s a major problem with the roll out of the updated “daily summary” email. It used to include overdue tasks for a week past their due date, as well as those current & upcoming. I relied on this extensively. Today my email showed tasks over due by only 1 day. I searched the site & saw this “Tip” - “Overdue tasks will not appear in Daily Summary emails.”
This is bad for me. Is there a way around this? Any hack to customize the email to include overdue tasks?
