My video feed to my iPhone 6 Plus keeps cutting out. So earlier today I was using the regular DJI Go app and had absolutely no problem with the video feed to my phone. So I decided to download the Litchi app to try out the features that it offers. After I used that app, I've noticed that my video feed cuts out at after a very short distance. Even when I switch back to the DJI Go app. What could be the problem?
