Mate not long had my inspire 1 and had the same issue, its in the camera setting within DJI GO there are three settings and I changed mine back to original number 1 setting and control returned for pan and tilt through use of button 2 on RHS rear of controller, hope this makes sense to you if...
G Day, my name is Peter, I live in NT Australia.
I have 7 DJI drones of differing types starting from 450flame wheel through the inspire 1, looking forward to chatting with like minded people in regards to the Inspire 1.
Kindest regards all,
peter n
