BuddyPress.org

Hi everybody.
I’m trying to figure out how to make auto-refreshing the activity stream when a new reply to a post is created.
It does automatically offer the refresh button on each wordpress heartbeat when there are new posts on the stream, but when there is a new reply on some of the existing posts, it does not. It also doesn’t automatically detect when an existing post is updated or deleted.
Is there a way to achieve that?
I’m running wordpress 4.9.2, and buddypress 2.9.2

Thank you!
