I have an inspire 1 x3 .. and Ipad air 2 .. I have not used the inspire for a few weeks.. when I switched it on I was informed by the DJI Go app on the ipad that I needed to upgrade. .. so following the suggestion on the DJI Go app screen in front of me... I pressed the upgrade button. .. After the "upgrade"... I can see the video feed from the x3 camera... but a message in red top left saying "signal lost".. and the bird has a fast flashing yellow light.... tried restarting everything ... even reinstalling the DJI Go app... but nothing... still still with "signal lost"... So much for my first flight in weeks as we had a bit of sunshine in Italy. . So now it seems I have DJI Go app version 2.8.0 and the RC is now version 1.6.0.. Please can anyone tell me what to do now. .
