I worked with WP Engine to get this fixed on a site so thought I’d paste his steps here in case it helps anyone else. This got activity feed loading activity (even on groups) while using BP Nouveau.
Here are his comments (Micah B):
so I did three total things. I cache excluded two URLs:
^/login
^/activity
and I turned a very specific setting on our end off – it was referenced in an old BuddyPress ticket that related to some of the issues I was seeing.
The setting name is “heartbeat_autosave_only” which I toggled to off
