I've found a similar question in the community but it didn't quite help me or I didn't understand it. I am in ArcPro for Desktop and I am trying to add a Domain. But when I click on my feature layer < Data < Domains I get "The Domains for this workspace are read-only". I saw a solution for ArcGIS Online, but how do I get this to work for ArcPro Desktop? Do I need to convert my layer to something? Or am I missing something?
