My Crystalsky was working great and then I did an upgrade. First, I know many will say that you should never upgrade software unless you have to, but I did anyway. I did the no-fly-zone update. Since then, even though I've logged in to my account it acts like I'm not, and restricts my flight distance and height. Each time I start DJI Go 1.0.7 that came installed it tells me to download the latest no fly zone data. I do it, try to fly, and I'm restricted even though I'm logged into my account. The map on the Crystal sky does not display the no-fly-zones. In addition when I start the app it tells me to upgrade to DJI Go 4.1. Problem is I can't figure out how to do that. When I go into the app it says I have the latest firmware (4.0.7) even though there's more recent software available. The Google Play store won't let me download DJI Go or the Google play App because it says I don't have a registered device. I can't register a device without the app. Plus DJI probably won't let you download the app anyway. Meanwhile if I hook my Mavic up to my iPad it flys just fine and the no fly zones are displayed properly . I have a Mac. If I could figure out how to download the app to an SD card I could insert it into the Crystalsky and it might upload it from there. I'm not certain because the website isn't clear. Any ideas?
