ArcGIS Pro 2.4.2 and ArcGIS Enterprise 10.7.1
I have a user with a User Type = Viewer, and Role = Viewer. This user is not able to edit a branch feature service in Portal Map Viewer, but is able to edit in ArcGIS Pro (i.e. Create a version, change to that version and edit features).
Is there an additional step that I would need to take in order to prevent the Viewer from editing in Pro?
