For some reason DJI GO doesn't synch top altitude, have a look on screenshot, all dates current accept for the altitude 17/07 ? All firmware current, app 4.1.3 Android
mine wouldnt sync all my flights..and it also didnt sync my (likely very illegal) max altitude pass i made.. and it recorded my top speed as 72.8MPH (totally impossible) during a out of my control fly aways i kept having with my ex-spark..
