Edge feeds option missing under edge screen options

[AC Question]

In S7 edge and Note 7,Under edge screen options, there is edge feeds option which is useful to see notification on edges when screen is locked. I could not find the same on S8+. Does anyone know how to get this back. This was the best part about the edge screen. If Samsung has removed this , Is there any way , I can install a previous version to get this back?Thank you.
