I also have the "only + -30° gimbal rotation" problem, but all of the solutions that heed results have failed. Even in the assistance software where you can change the gains of the gimbal, the sliders are nonexistent not allowing me to adjust it manually. In the link shows pictures.  I have uninstalled and reinstalled the software, run 3.6 & 3.8 versions, and reset the gimbal. All no the same dilemma.
