UI16: Activity Formatter does not show on reference popup with Sys_popup view - Known Error

UI16: Activity Formatter does not show on reference popup with Sys_popup view Description After adding the "Activities (filtered)" formatter in a Sys_popup view on a table, it does not appear in the reference popup preview. This formatter was displayed in earlier pre-UI16 versions. Steps to Reproduce

Customize the Incident popup view layout by going to the URL .service-now.com/incident.do?sysparm_view=sys_popup.

Add the Activities (filtered) formatter to the Sys_popup view.

Navigate to Configure > Form Layout . Scroll down in the slushbucket and add the Activities (filtered) formatter to the form. Click Save . Add a name in the required Caller field and click Save in the Incident popup view window.

Go to an Incident list.

Hover over the reference icon ( ) of any incident record in the list.

Note that the Activity feed is omitted from the popup view.

Workaround This is expected behavior: the UI16 design features a new activity stream.
