I open the DJI APP. It tells me the RC needs to update. The software already installed is 1.6.0. It prompts me to download. I download. It updates to 1.6. Promps me to delete firmware downloaded. Prompts me to restart RC. I restart RC. It tells me RC needs to needs to update.............. Feels like I am groundhog day. It has 1.6 installed so why does it need to update?
