Hi folks, Apologies for this. We have a number of databases at MN - a primary that your messages go in and a number of replicas that we read from for searches etc, including for the last 15 minutes search. Unfortunately the replication process has got delayed / fallen behind and the replica thinks there are no new messages (as it hasn't seen them yet.) We've fixed the underlying issue and replication is catching up. It should be fixed within the next hour or two. Sorry about this.
