We’ve been alerted to a bug in the recently-released Replyable 2.2.6. We are addressing it now and hope to have a fix out today or tomorrow.
The issue is that authors, in some cases, may not receive notifications of new comments on posts which they have written.
We will post here again when the update has been released. In the meantime, it’s perfectly fine to roll back to 2.2.5, if you would like.
