In one Discourse instance, we have one ActivityPub actor for a tag set to first post only, and new topics using this tag are federated automatically.
In another Discourse instance, we have several ActivitPub actors for various categories set to all posts, and… new topics won’t federate automatically. They need to be federated manually using the admin dialog in each topic.
I have checked the settings, and I believe both Discourse instances have the same. Do you know what is happening and how can we we have all new topics federated automatically?
