I've seen a tutorial that was quoted on the forum that allows speed settings to be changed. "Advanced Gimbal Settings" appears under the Control tab in the tutorial, along with "Gimbal Mode" and "Gimbal Calibration". However, on mine, it does not.  The  only options are  "Gimbal Mode" and "Gimbal Calibration". I"ve updated the firmware recently, so I'm stumped.  My goal is to get smooth video as I slowly rotate the camera while the drone goes slowly straight up.

Hello, Alexis. Thank you for reaching out. Please note that after upgrading DJI Fly V1.8.0 or later, the advanced gimbal setting function has been integrated into the "Gain&Expo Tuning" option. Please go to DJI Fly app > General Settings (3dots) > Control > Gain and Expo Tuning to modify. Hope this helps. Have a nice day ahead.
