Just received p4p back from cable replacement. They flew it and was fine. I can't get the controller to connect to drone. The drone has all 4 solid red lights. I did the bind routine and controller says it took but screen shows "aircraft disconnected" and little light on side of drone is flashing red (the same button I pushed to bind. They did a software update before flying at service center using my controller and drone. I'm lost for what's next.
