_bp_get_user_meta_last_activity_warning( null $retval, int $object_id, string $meta_key, bool $single )

Backward compatibility for ‘last_activity’ usermeta fetching.

Description Description

In BuddyPress 2.0, user last_activity data was moved out of usermeta. For backward compatibility, we continue to mirror the data there. This function serves two purposes: it warns plugin authors of the change, and it returns the data from the proper location.
