A couple of weeks ago I noticed that I start getting random messages on my phone saying, "Unfortunately, DJI Go app has stopped." This was happening almost daily and I wasn't event trying to use the app. It wasn't opened or anything. I have uninstalled and reinstalled it several times with no resolution. I also tried uninstalling, restarting (and powering off) and then reinstalling and same thing. I am able to use it on my wife's iPad but not on mine. I have the S7 edge. I have successfully use it with the S7 edge for the past several months, the problem only recently started about 2 or so weeks ago. Any suggestions?
