bp_activity_add does not appear to fire when blogs in the network publish

[lordmatt]

I hook bp_activity_add to invalidate a cache when a new activity is recorded. The function does not fire when any blog in the network posts.

Hi thanks for your feedback.

Can you confirm BuddyPress is network activated?
Are activities generated when blogs post?
Where is located you custom code? (mu-plugins, bp-custom.php, somewhere else)

Can you try using a higher priority for your hook to see if it fixes the issue?
eg: add_action( 'bp_activity_add', 'your_hook', 9 );
