I have the Phantom 3 SE, I use the iPhone 6S with the latest IOS and I face the same problem, no video. I’ve tried to uninstall the DJI GO and keep only the Litchi but it didn’t work. The Litchi support told me they didn’t receive the SDK from DJI so they can not develop the app, I’ve asked them if they tried to fly the SE with Litchi and they didn’t try it. Now I sent a message to DJI to understand if they intend to send the SDK to the Litchi. I just want to fly my SE with my goggles without having to spend so much money in the DJI goggles.
