When you land you simply need to power down the aircraft normally, remove the battery, put the new one in and power the aircraft back up. The remote should stay powered. If there are any issues you can always go back to the main menu of the app and open the mission planning screen again to force a new connection.
It sounds like you either have an issue on your device or you might have some other drone related apps running in the background. Make sure those are all closed before using Map Pilot.
