I recently deployed the Sewer Data Management for ArcGIS Online Solution. After adding my data, I wanted to add a new field and domain to one of the existing layers but, so far, I’ve only been able to figure out how to add the field. There doesn’t seem to be a place to add a domain in AGOL and when I try and add the domain in ArcPro, it says the domains are read only and cannot be added to.
I’m sure I must be missing something because I’m just trying to create a new domain which should be pretty simple.
The place to access the domains in AGOL is by clicking on the field in the Data tab and accessing its "List" as described here: https://doc.arcgis.com/en/arcgis-online/manage-data/define-attribute-lists-and-ranges.htm#GUID-6E9A9...
Send screenshots of what you see for that field.
