I updated firmware, got a confirmed text file, but now can't connect to remote. DJI says you may have to relink after firmware update but I can't find how. Any help is appreciated.

Thanks,

I restarted both remote and p3 several times now all of a sudden it connected. Good to go......I guess

There's a link button on the side of the aircraft. Believe it on the opposite side of the sd slot just above the gimbal mount.  Small hole, may need paper clip to push. Exact location is in manual.
