Hi @Bryan_TeamKickstart, this update was expected and took place just a few days ago as @Bastien_Siebman mentioned.
The fact that a search for task due in the future returned tasks in the past created a lot of confusion with reporting. We heard that via many channels including the Forum: Advanced Search > Completion=ANY and Due Date Within Next 30 Days, Search due date in next xx days not working - #8 by tom.marsh, Is it a bug or am I doing something wrong? Due dates in reports) hence why we’ve decided to correct this behaviour.
We’re not planning to revert this update, but if you’d like to see overdue task included in your reports, we recommend using a time range instead of tasks due in X days, this will return all tasks due in the future as well as overdue tasks!
