We are not aware of such a problem. I tried to reproduce it on my side with a simple project, just a ScheduleView with empty AppointmentSource and have no problems with drag and drop. Maybe you are doing something different. Could you please send us a project where you are reproducing the error, also the exact error or StackTrace would be of help in order to pinpoint what is the problem.
