I bought OsmAnd+ when the navigation still worked somehow. I took an account that each newer version will provide more and more fixes and upgrades. But it worked totally different. With current release the navigation is totally disaster and useless anymore. The most I hate it now is very long time to calculate the route  it takes so much time that I can ride few kilometers and navigation is still in calculation. And when navigation lost the route it starts to calculate it again and it takes next minutes  where I can ride next few kilometers without map. It didn't work that way before. It is dissapointing considering the fact that google maps is free and has offline mode now (not full offliine  but it navigate much better). I don't know what filters You have implemented into it  but when I zoom map i clearly see that my car is off the road.
