There are several easy solutions to the World Imagery blank grey tile "Map data not yet available" bug. See:

https://developers.arcgis.com/rest/services-reference/map-tile.htm

and

https://github.com/openstreetmap/iD/issues/4327

... if ?blankTile=false is added to the tile request, a 404 is returned instead of the blank tile. Alternatively the HTTP response includes the header "blank-tile": "true" for missing tiles.

This should be enough to prevent the display of the grey "Map data not yet available" tiles.

  FYI the other ESRI layers (e.g. "Shaded Relief") also show blank tiles at higher zoom levels.

  This bug does not happen on the web version... perhaps you can ask them how they solved it?
