WordPress Multisite + Buddypress

Thanks for this report. I have not used this configuration before, and given the complexity, I’m not surprised that it’s not working out of the box.

Because immediate notifications are being sent, I’m guessing the problem is not with the general subscription mechanism. You can verify by checking the wp_bpges_queued_items table to ensure that there are pending ‘weekly’ and ‘daily’ items.

It’s likely that the problem is with the digest triggering mechanism, which works via WordPress’s cron system. As a first step, I’d recommend checking https://wordpress.org/plugins/wp-crontrol/ to see whether there’s a single digest event for the whole network, or whether there’s one for each site.

It’s also possible that the digest item query is not pulling up items from secondary sites, possibly because of the way that groups are filtered out by BP Multi Network. Can you confirm that this is the plugin you use for Multi Network? https://buddydev.com/plugins/buddypress-multi-network/
