Hello I would like to use GPX files from dual sport.com maps.. I put the GPX file directly in the navigator gpx file. on my android 7.1.1 phone. Next when I go to open the app and look in Routes - GPS Files : it does not show the GPX file I manually put in the folder. However I do see a route I recorded with Navigator app.... Also when I click on the GPX file directly (in the folder) to open it says "Can't find app with which to open this file"
