text: Do not expect it to show up immediately. The map you see is build from countless small "tiles" typically 256*256 pixels, one set for each zoom-level, produced by a "tileserver". Depending on how busy this server is, it takes from a few second to maybe a couple hours for new features to show up. 
  In fact I can see the name on one zoom-level now. Try zoom in or out a bit and you will see it too.
