Are you sure the connexion is lost ? because I have almost the same issue (see https://www.drivemodedashboard.com/forums/topic/controller-reacts-as-if-on-application-view-while-is-really-on-map-view/ ) and at the beginning I thought the controller was no longer working ; but (for me) it works as if it was on applications view while the displayed view is that of the map.
