Guidance missing most of the turn info

[mdykierek]

Description

This report concerns ALL symptoms described in #19016.

1. First case
   https://osmand.net/map/?start=49.792172,18.935277&end=50.256065,18.865773&profile=car#9/50.1492/18.7592
   The turn I missed: https://www.openstreetmap.org/way/24931388.296875
   Then I ignored the detour recommended by OsmAnd (because it was much longer) and went this way: https://osmand.net/map/?start=49.792172,18.935277&end=50.256065,18.865773&via=49.844251,19.068453&profile=car#16/49.8424/19.0549
   It kept giving proper turn info until I reached road no 1:https://www.openstreetmap.org/way/273487768.484375
   after that the only turn info was regarding intersection (not even highway exit, but traffic lights) here: https://www.openstreetmap.org/way/168533691.734375.
   About here: https://www.openstreetmap.org/way/243067680.265625 I stopped the navigation, set the destination again and it was OK until destination.
   BOTTOM LINE IS: when route is recalculated because of deviation of already computed route, the turn info fails at some point. It was not immediate. It "realized" that I made a detour, and computed new route, then guided for a couple of manouvers, then forgot most of the intermediate points.

2. Second case
   I almost missed an exit just yesterday going from Ruda Śląska in Poland to Jablunkov in Czechia. I was supposed to go through Bielsko-Biała, but decided to go through Mikołów and Skoczów. Furthermore I took a shortcut to bypas Mikołów (https://www.openstreetmap.org/way/35477075).
   This made OsmAnd re-calculate the route at least twice.
   As the result turn info was lost again! The only guidance was for the roundabout in Cieszyn! (https://www.openstreetmap.org/way/87496227)
   So all lane assist on intersections and traffic lights. No exit to S52. This slowly becomes a showstopper.

I have the same issue since I downloaded v 4.7.17, when using a gpx track and using the attach to roads option, it will give me the right turn by turn guidance for a while and after some time it stops doing that and just gives me a grey straight ahead arrow with some random distance till the end of the route

@mdykierek please indicate, what is proper turn info for you? Voice instructions, info in the next turn and (or) lanes widgets?

I simulated the deviation from your route using route link and Deviation.gpx.txt, and I don't see much difference in route info (screenshots from navigation > details > route info, the first one was made before deviation, the second - after deviation). The route was recalculated multiple times.

As you can see on the OsmAnd web site, the most turn info is grayed, so it should not be announced

[mdykierek]

By "guidance" I mean voice, turn and lanes. OsmAnd behaves as if there were no "manouvers" i.e. exits, turns from were I am until certain arbitrary point. The route seems ok and complete when map is zoomed out.
It never occurs in simulation. I don't recall it fail when the route doesn't get recalculated by a detour or my arbitrary decision to take a shortcut or bypass a traffic jam.
When I see it happen, I have to stop the navigation and set the destination again. Which is 1-annoying, 2-dangerous.

[DmitryAlexei]

@mdykierek I still cannot reproduce that issue. Please try OsmAnd beta from Google Play, and tell if it works more stably when recalculating the route.
We can also try to reproduce that issue using your driving profile. Go to menu > settings > your driving profile > export, then add .txt extension to post it here, on GitHub.

[mdykierek]

So OK, we can agree that the problem exists but you cannot reproduce.
If you would like for me to provide any data/input let me know. Tomorrow or on Friday I plan to go a route that I know it occurs (Ruda Śląska - Tarnowskie Góry = lost exit, first guidance for the roundabout exit).
I could record the track and screen if of any help to you.
I won't use Beta as I will need offline navigation in a couple of weeks. I need OsmAnd+ to be stable.

[DmitryAlexei]

The issue may depend on your profile settings.
If you don't want or cannot attach your driving profile to that issue (so we could reproduce it), please try recalculation with default profile:

• go to menu > settings > + New profile > create a new driving profile
• navigate your usual route using a new profile
• we will also be grateful if you save (and then send us) the logs immediately after the problem appears (menu > help > three dots in the right corner > send logcat log)

I don't know if this is good or bad news. I went the route and it didn't fail this time. I did not change anything in the navigation settings, however I reset the zoom levels to 100% for both text and map magnifier. That would be very strange factor.
