In our C++/Qt runtime application, we want to use a soil survey map as basemap.
ArcGISTiledLayer* tiledLayer = new ArcGISTiledLayer(QUrl("https://server.arcgisonline.com/ArcGIS/rest/services/Specialty/Soil_Survey_Map/MapServer"), this);
_map->setBasemap(new Basemap(tiledLayer, this));
This used to work fine.
Since a few weeks we started to re-write our application using Runtime SDK 100.0.0 (instead of 10.2.6), and I hadn't used this basemap for a while.
Now I wanted to use it again, but the map is incredibly slow, or even not loading at all. (see the picture in ArcMap)![](/legacyfs/online/365564_Soil survey map.jpg)
What's happened ?
