When 3D model showed up, it worked awesome, quick, smooth, no problems. Unfortunately, since some time it stopped working. When I click on 3D I get this black globe with izolines and wait for the map to render, nothing happens 1-2-5 minutes, still nothing.
Then I realized, I can interact with the globe and I have to click on layers to show up. So previously it was remembering the last used layer, now I have to double-click it to get it to work: 3D -> layer.
