What’s happening?
The "Extend Booking" button does not perform any action when clicked on a project's Resource Reconciliation tab. Users report that no bookings are created, and no error messages are displayed.

Reason:
The functionality may not be working due to the absence of overlapping working hours between the resource and the project. Simply being in the same timezone is insufficient; there must be actual overlap in their working hours. 

Resolution:
Verify that the resource and the project are configured to have overlapping working hours during the period in question.
