When editing an SDE Feature Class (Versioned and Editor Tracking Enabled), which is published to ArcGIS Server as a Feature Service in AGOL for organizations, the edits are recorded as esri_anonymousm, not the user name of the editor. The user name of the editor is recorded when using Hosted Feature Service in AGOL.
I would like to see the same functionality where the username of the editor in AGOL is recorded into the SDE Feature Class when edited through AGOL (AGS Feature Service).
