Yesterday I downloaded the DJI Fly 1.2.5 app and can't use the "Allow Upward Gimbal Rotation" function. It's the first time I tried to enable the function since getting my new MM2 a couple of days ago. I've tried setting it when the AC is grounded and when it is in flight and it doesn't work either way. The function shows in the app as a gray color and when I try to slide it to the right nothing happens. Any pointers as to what I should try next.
