Last year I was creating routes for my motorbik in the following way>
I opened a gpx, calculated a route with the option "calculate route between points" enabled and the option "Calculate a osmand route for the fiorst and last routepoint" disabled. This took a while.Then I saved the calculated route,
On my motorbike I could open the precalculated route and almost immediately start driving. When I left the route Osmand tried to get me back on track and that worked great.
Now this procedure does not work anymore in version 3.6. When I navigate a precalculated route and I am off track Osmand no longer tries to navigate back to the route but in stead I see a straight line to the starting point.
When I open the orginal gpxfile and calculate the route again (takes some time on my old phone) then the navigation works as expected.
So saving the calculated route and reopening this route does not work properly.
Also I noticed that the waypoints on the route are announced although I have turned all announcement options off.
