For whatever it's worth, the DJI Go app on my iPad Mini 2 would not start after I updated my P3P to the latest FW (1.6). Only after I deleted it and reinstalled it did it start functioning again. The symptoms were that it would launch but then immediately end. I did all the usual closing of apps and a power off/on on the iPad but that did not make any difference. The one thing I noticed was that I also lost all my flight historical data with the reinstall. With that revelation, I now know where they are stored and I will start capturing them in an offline file in the future. I thought that those logs were retained in my DJI account but I guess not. No big deal but now I have more knowledge going forward. I also now have an account with Healthy Drones and will send my logs there.
