Hi everyone! Where in the DJIGo app can I turn off the front LED lights? I've seen it done, but cant seem to find the option in any of the menus. Thanks in advance!

in advanced setting on the bottom turn off front leds

Heebus is right. And you need to turn on the drone when you change the settings of the drone.

There's another LED shutoff option in the camera menu (under the little wrench)..    You can select "Front LED auto turn off".   This will keep the lights on, and only shut them off when you take a photo or video.   This is handy under low light when you want to see the drone, and only want the lights off when capturing video/images.   You need to be connected to the drone to see and select this option.
