It all started after buying a spare battery. As I had not saved the Dji Go app on my micro card I decided to update the Go app on my Android tablet. After doing this and updating the RC , AC and both battery's I opened the simulator to test it out before flying for real. It keeps telling me " You have reached your max height and distance ". Although I was not prompted too ,I tried to log in as I was aware this should solve the restrictions. User name and password entered, " Login failed, try again " is all I get. I can login with same details on my laptop with no problem ? All was working fine before these updates. Please help before I start kicking next doors cat. ;-)
