On December 6, 2021 from 1:37 p.m. to December 8, 1:55 p.m. PST, some customers may have detected that messages weren't loading from DMs and private channels when scrolling through their message history.
After identifying the issue to a recent change made to how the client fetches messages, we reverted these changes, which resolved the issue for all impacted users.
3:25 AM PST
We've deployed a fix, and messages from DMs and private channels should be loading properly now.
Please reload Slack, by pressing Command/Control + Shift + R.
We apologize for the disruption, and will return with an issue summary in the next 24 hours.
2:34 PM PST
We are continuing to investigate reports of messages not loading correctly in private channels and DMs. Clearing the app’s cache may resolve this in some cases.
Note: We’ve edited the wording of our previous update to more accurately reflect this issue. Messages are not missing, but may not be loading correctly.

Some messages from DMs and private channels aren't loading. We're currently investigating, and we'll keep you posted as soon as we have more information. We're sorry for the disruption.
