Watched 3 vids and read the manual on "password reset" and went thru the motions with mine to no avail. AC is connected and the DJI GO app. is up and running, but when I go to "reset password", I don't get the "spinning wheel" to show it's working to reset it. When I hit the prompt that says "restart drone now?" and hit "OK", nothing happens, just a frozen screen. I would like to change the default password of 12341234 to my own, so someone can't fly-off with mine. What did I miss? Thanks in advance for any help with this. H.P.
