Hello, I have the DJI Phantom Vision and recently a problem which is intermittent and happened a couple of times now. I do not get a link between the Remote Controller and Receiver. The procedure: 1. I switch on range extender, remote controller and then the phantom vision. 2. After the boot procedure (sound and lights) the visions two lights are flashing fast in yellow color. 3. No link is established between DJI Vision app on the iphone and the visions camera. 4. After some time the remote controller light starts flashing and beeping. > Switching components on and off does not help, following the link procedure in the manual "Link between the Remote Controller and Receiver" pressing the button at the vision does not help. Despite recycling the procedures over and over again I cannot get a link and have to cancel the flight. I tried to use the phantom a couple of days later and suddenly everything works normal, I have no idea why. Questions: Is there anybody who had the same problem? Do you know how to rectify the problem? Thanks for your help.
