Well, to begin with. Got everything ready, started controller, then app, the quad. Everything looked good, till it took me to the registration screen. Would not recognize my email address, so I backed out and it seemed ready to go. Left it overnight and tried again this morning. Still would not take my email. Tried a few more times, and now the controller says disconnected. Tried everything I can think of, except rebinding the rc, but not sure how to do that. Any ideas, help? Thanks.

there's a button on the side of the gimbal you press.   Read the instructions on binding.   It's in there

It must be linked, because it does control camera movements, but no picture.

Well I got it connected again (new cord), but system still won't accept my email! DJI...can you fix that at your end?

Ok then! Things are starting to get better. Had to register with DJI North America before I could log in to register my P3, so all good now. On to IMU calibration.

And it wasn't the cord causing the issue. Seems starting sequence of components has an effect.
