If you have a logbook you filled out with contacts on a POTA activation, and you check the map, it shows the starting point as your default location as expected.
If you then realize you never set the location to the POTA park, and you change the location on the logbook and save it, the map starting location for all the contacts does not move to the new logbook location you just saved. I.e. it still shows all the contact lines going from your home base instead of the newly saved POTA park location.
PS. the Map feature and Band Plan feature are AWESOME, thank you.
