When I got my bird back from repairs, this was the drill: turn on the remote, start up the Nexus. The Go app would load, but the camera wouldn't connect. Restart the controller and the little window would ask Litchi or Go? Choose either and "just once or always" comes up. And then it connects. Today Go started automatically with every start, switching to Litchy would connect, but no camera. Restarting the controller always brought up Go, which worked OK, but the little window allowing me to choose between them wouldn't appear. FWIW, I don't really expect a solution, I'm just venting until I figure this thing out.
