@Jakub-Kraft-0 I see. Vector had worked for me for the past couple of weeks and I got quite used to it (the topography looks better than the non-vector version), so in a way it feels like a step back now without vector map. Hopefully it will become available soon again.
In my opinion, the biggest drawback of the vector map, however, is the display of route names on the raster layer. It is much less reliable than on the non-vector map, often appearing only at certain zoom levels or not at all. On Mobile, rotating the map by 180° can sometimes help when a route name wouldn't appear otherwise, but this is inconvenient, and the workaround is not possible on Web Mapy.
I hope your team can make route-name rendering more robust, so names appear consistently across a wider range of zoom levels and viewing angles.
