I created new domain values for a field in my attribute table. When I shared the new map on ArcOnline, the domain values disappeared. When I open the map from the portal in ArcPro they are still there. How do I ensure the shared map online is the same as the one I see in Arc Pro?
Are the domains integrated with subtypes? If it does, then try to bypass the subtypes option and set up domains directly on each field.
