See the north east corner of this ride, I think it was the last time I used the courses function.

Although i agree that course navigation is not seamless, the error shown here is a no signal example, not an off course problem. The 3.30 firmware appears more robust now with course navigation. Also, for better turn notification, use bikeroutetoaster to create a tcx file with 300 ft turn alerts from the original ridewithgps file. It is much more useful and even allows adjusting the virtual partner.
