For the past couple of days I'm getting a red No Signal warning at random times. I always retain control but just lose live video getting a blank screen. It can come and go randomly before taking off and when flying. There is no correlation with anything , ie videoing or not, distance from controller, surroundings etc. and I have tried various changes in settings with no improvement. Is it a problem with the bird, controller, DJI GO app or my iPad air2? I have installed the most upto date versions of everything. Also why has it just started after a couple weeks without a problem and is anyone else experiencing a similar problem? Should I just hope the new firmware update supposedly coming tomorrow solves the problem? Thanks to all and enjoy the holiday weekend.
