Question: Newly created comments are replicating properly across the Publish and Author instances. However, when deleting comments, the comments are removed from the Author instance but *not* the Publish instances. No exception is being thrown in the logs. Where would be the best place to look at troubleshooting this issue?
Answer: Try using the Communities (moderation) console on Author to delete comments instead of deleting them in-context. From http://localhost:4502 > Communities
