I installed the P2 Assistant 3.0 on my PC. When I opened it while attached to my P2Z, it automatically installed the v3.0 firmware upgrade. I was not happy about not being given the choice to upgrade. But then, let's see what happens. I went through calibrations on P2A 3.0 on both the P2Z and controller. I have not had a chance to fly my P2Z but I was playing around on the bench and noticed the 2D gimbal did not respond to the controller slider. I have not seen anything here describing this issue. The GoPro was on and I did not have the USB connected to my PC. I decided to downgrade back to v2.0 but I still have this problem. Any ideas on what I did to screw this thing up?
