Previously, deselecting the Show in the Console option for the highlights panel in Layout Properties on a page layout removed both the console highlights panel and the Case Feed highlights panel when users viewed case records in Salesforce console tabs or subtabs.
Now, when compact feed is enabled, deselecting the Show in the Console option for the highlights panel in Layout Properties replaces the console highlights panel with the updated Case Feed highlights panel on primary tabs. The Case Feed highlights panel is still shown on console subtabs.
To remove highlights panels altogether from both tabs and subtabs, use the page layout to remove all of the fields from the Case Feed highlights panel.
