New to ArcGIS Desktop and currently testing out publishing a raster tile to WMS for use on ArcGIS Online.
This seems to work in ArcGIS Desktop, and previews under 'My Content' in ArcGIS Online - but when I go into the Map Viewer it is "incompatible with current basemap".
This is the same regardless of which background map I show, or indeed if the background map is switched off!
Am I missing something obvious? Any help much appreciated.
