Hello...after trying the factory reset to sort my no maps issue I am still getting a Network Unavailable message on my Offline Map Download page. WiFi is all connected and sign in was OK... Anyone had this and found a cause and or fix?..Thks P4P+Well after spending over a hour with online support which was useless and patronising I just gave up and did a factory backup and reset, and bingo maps are back and everything is good, update now stable... so if anyone else has a problem just do a reset it's the second time it's sorted a issue, now have drone in the air and all is good..
