Hi, I'm using the DJI Spark with Remote controller, updated all firmware and software to latest versions (30th September 2017). It connected with iPhone 6 Plus (Latest iOS11) and I was able to fly for a few minutes but then it disconnected and only the camera was working. The screen was only showing the Red camera record button, the flip video/camera button and setting button but NONE of them are responsive. I've tried restarting phone, and DJI go app as well as restarting the remote controller and drone, but it still shows a screen with only record button and settings button which are un-responsive. Anyone else having the same pro blew on the new latest firmware ? I've also tried to delete and reinstall the DJI GO App but doesn't seem to work. I've attached a screenshot of what the interface on the screen shows (but none of the functions/buttons work when pressed on) Any idea?
