Hi. I am having trouble with my V2+ gimbal ever since I updated the firmware. Now, when I power up the camera points straight ahead and I can see what it sees just fine on my iPad. The problem is when I try and adjust the vertical movement of the camera. It just goes right to the top of its travel and stays there. It does not matter if I touch the down button or the up button, the green slicer just goes right to the uppermost position and stays there. Any ideas? Thanks in advance.
