If your DJI Go 4 app is not working, the first thing to do is ensure that you have a stable internet connection. The app requires internet access for some of its features to function correctly.

Sometimes a simple restart can fix issues with the app. Try restarting your device and relaunching DJI Go 4 to see if the problem persists.
Ensure that your device is compatible with the DJI Go 4 app. Not all devices are supported, and using an incompatible device can result in the app not working as intended.
