I succeeded in activating my new DJI FPV unit. The drone and goggles are fine. However, it says the RC isn't connected and however many times are restart the units it doesn't connect. Is there a binding issue? How do I bine the RC to the drone and goggles?  Or what else is incorrect here?

I did find the link below which explained how to connect the drone to the remote : holding down the button on the drone till it blinks, holding on/off button down on the remote until it beeps and then they pair. Or they don't! The first few times I did it, I'd get an acknowledging beep that they were connecting, but then after waiting minutes they wouldn't lock in. After those two instances, when I restart the entire sequence and hold the power button on the RC for 5 seconds, it doesn't even try.
