Now I have the new phone with the newly installed Locus Pro.
Two days ago we had the 147km road trip on bikes. After 100km the problem I described here (http://forum.locusmap.eu/index.php?topic=3372.msg28287#msg28287
) appeared again and made me to cut off the passed part of the route in order to have possibility to continue the navigation. This method with cutting off is the only way to continue navigation since it was implemented in Locus.
So today I had to conduct the experiment. Before riding on the "A-104" road (see the screenshot) in the bus I created an experimental zigzag route. In the first 3-4km the navigation algorithm had the good job. But at one point it stopped and started to draw me to passed point. And the menu item "Nearest point" was hard redirect me to that passed point.
That is usually in such cases in the real world it is no a further opportunity to continue the navigation or even restart it! It is always draw you to the one distant magical point... The cutting off all the passed way is the only method.
