Black Background with Grid

[KevinFox]

I'm using ArcGIS iOS app using maps created on ArcGIS Online. The iOS app show this black background with a gray grid in areas not covered by a polygon (see attachment). Using ArcGIS Online the background in the normal white. Is there anyway without publishing a new basemap to have the white background show in the iOS? Any other suggestions?

I know this does not help but we have the same thing but our background is grey.  Did anyone figure it out?
