One of my P4P v2 decided to fall from the sky for no reason. I bought a new P4P v2 and want to link my existing v2 PLUS controller to it.  Both are P4P v2.  The standard procedure does not work.  What is the fix?  I've tried many times and no connection is established.  Thanks.

DJI wasn't too helpful.  What else!  On the phone call they simply went over the linking procedure as in the guide, that I had already tried ten times.  Then they said I need to send the controller in for 'analysis'.. The thing was working fine with one aircraft.  I just couldn't swap.  I updated the system firmware.  No go.....

It's lonely out here....

Thanks for all the help[!
