I have set the default base map in my organisation>edit settings>map as 'Base Mapping Colour'
From my content page if I add a new map it opens up in some location outwith the default extent I have specified. From that map if I then click new map it opens as expected. Am I doing something wrong creating a new map from My content?
I want to create a new base map for ArcGIS online.
If I create a new map and paste the map service URL for my black and white map the default colour map is there as a base map - how do I remove that or assign my black and white version as the base map?
