Unable to configure fields in activity stream - Known Error

Unable to configure fields in activity stream Description Unable to configure fields in activity stream (no funnel) because the activity stream expands the entire width of the form. Steps to Reproduce Navigate to a record (such as an incident) with an activity stream. Identify a read-only field (such as Priority ) on the form. Click the menu icon and select Configure > Form Layout . Move the read-only field you identified in step 2 directly above the Activities (filtered) form element. Note that the read-only field is displayed , but the activity stream expands the entire width of the form and you cannot configure activity stream fields using the funnel icon . Workaround No workaround is available. The issue no longer occurs as of the Istanbul release.
