I updated the DJI Go app for Android to the latest version released yesterday. The docs state the RC was to be updated too but I did not see this as part of the process. After updating Go app, a message indicated new firmware was available for P4. I downloaded and installed it and now I get a red blinking signal lost message. I can see the camera and move the gimbal but no luck to start the P4 and eliminate message. How do I reapply an update to the RC? Is this not part of the update process via the GO app?
