Issue summary:
On January 18, 2022 from 4:40 p.m. to 7:30 p.m. PST, a small number of users were not able to view PDF and Office files within Slack and saw a broken file icon instead.

This was the result of a recent code change that caused the files to fail to load.

We've released a fix for this and PDF and Office files are up and running once again. Apologies for the earlier trouble and thank you for your patience.

3:20 AM PST

The issue has now been resolved. Please try reloading Slack by pressing Command/Control + Shift + R.

We're sorry for any inconvenience this may have caused.

7:41 PM PST

Some customers are having trouble viewing and accessing files within Slack. We're working hard to resolve the issue as soon as possible and will be back with an update once we have more information to share.

6:12 PM PST

This issue should now be resolved and we are currently working with customers who have reported that their channels did not automatically reconnect after re-upgrading to a paid plan to re-establish those connections.

If your team recently downgraded to a free plan, then resubscribed to a paid tier and observed Slack Connect channels not reconnecting, you can choose to manually reconnect those channels or reach out to our support team at feedback@slack.com for assistance.

We've identified the root cause behind the issue and are working on getting things back to normal. We'll have another update as soon as we have any further information to share.
