We've heard feedback from clients that they don't want the creation of Bookings in the Crew Planning App to add or remove people from Projects. At the moment, if a new is Booking is made on a Project for a person then they are automatically linked to that Project and if all Bookings for a Project are removed for a person then they are automatically removed from that Project.
Please add your support to this feature request if you don't want Crew Planning App to automatically affect Project linking.
