Last update from Ably
Between about 14:00 UTC on the 20th and 17:00 on the 21st, on channels with the persist last message (https://ably.com/docs/channels#rules) channel rule enabled, attachments with `rewind=1` in situations where the most recent message was published over two minutes ago but still somewhat recently (and where the channel has been continuously active in a given region since the message was published) may not have had that rewound message correctly delivered to the attaching client. We apologise to anyone whose application was affected by this.
