## Timeline of updates

- **resolved** 2026-10-20 13:00 UTC: 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.
