I have Upgraded To the Latest Firmware, v1.8.80 for the Phantom 3 Pro and the firmware on the remote. Before Takeoff I have selected Multiple Flight Mode on , Beginner Mode Off, Maximum altitude set to 300. When I takeoff I go about 40 feet away and about 80 feet high. I then select Function mode but do not get either the IOC menu nor the Icon on the top of the DJI go App. This also happened on the previous firmware. Not sure what I am doing wrong?? Any ideas or suggestions would be greatly appreciated.
