Betstoute has some apparent problems.
(1) I can set multiple places, but if I ask to navigate, I only see the first one
(2) If I ask for a route between two places that are not my location, then Navigation will always revert to my location anyway.
(3) If I exit navigation, I am dropped back to vanilla maps, not bestroute
(4) There is nowhere to select a location on the screen by simply touching, then using that as one of my locations
I have emailed the developer about this, but feel free yto jump in if I am wrong, mor if there is a workaround.
