I am having problems with the vertical camera roll adjustment, ... 1st it was slightly pointing up so that the props were in the video & photo shots., ... So I tried adjusting the camera roll from the menu, which very little ... also tried resetting it in advanced options ... trying to get it to tilt forward slightly, it is now frozen in a straight on shot position & will not move at all, ... any of You "Pros", out there help a novice, as I want to take the drone to Mexico in 2 weeks & need to be able to have a working gimbal to capture shots I want, ... thanks all, Dave
