Last week, I had additional options for basemaps in ArcGIS Pro - many of the basemaps offered in ArcGIS Online, such as watercolor, newspaper, human geography, etc. Now, they've gone missing. I'm in the same project file, and I still have one of those basemaps active and it's working; if I select another one, though, I wouldn't be able to get it back.
At some point, I remember seeing a message that I wasn't signed in but now I am. Am I able to access these by signing out? Is that the problem? How can I enable them while signed in?
