Based on the ESRI documentation for ArcGIS Pro, I thought that I could drag and drop files from either the Catalog pane or Catalog view into a map. I just installed Pro 2.5, and I can only drag and drop from the Catalog view. I have not been able to drag a file from the Catalog pane onto my map; I have to right-click the desired file and select the "Add to Current Map" option to add files from the pane, while dragging and dropping from the view works fine. Is there something I'm missing? I encountered the same issue whether I was trying to add rasters or shapefiles.
From Catalog pane, catalog view, and browse dialog box—ArcGIS Pro | Documentation :
The Catalog pane docks in the ArcGIS Pro application, providing access to items in your project and the active portal while you work. After browsing or searching for content, you can drag layers onto maps, datasets onto tools, tools onto models, and so on.
