Update

The re-processing of the backend job to attempt to serve queued Events API requests continues, and we expect this to take a couple of hours. 

If you are experiencing the separate symptom relating to Slack Connect where some users are having issues @-mentioning channel members, please reset your cache and refresh by following the below steps:

1. Open the Slack desktop app, then click Help in your computer's top menu bar. (If you’re on Windows 10, click the ☰ three lines icon in the top left of the Slack app.)
2. Select Troubleshooting.
3. Click Clear cache and restart.

We will continue to provide any new information available along with confirmation once the re-processing of the backend job is complete.

Update

We've began re-processing the backend job to attempt to serve queued Events API requests over the next several hours. Once complete, new requests should begin to trigger as expected.

We will continue to provide relevant updates and confirm once this process is completed.

Cause Identified

Users may still be experiencing issues with some custom apps/bots or Slack Connect not working as expected. We have identified the cause of the issue as a symptom of an earlier incident, and are working on a solution with the highest priority.

We will update with more information when available. Thank you for your ongoing patience while we work on this.

Investigating

We're receiving reports that some custom apps/bots may not be working as expected in Slack. This is related to Events API and is a symptom of an earlier incident about trouble connecting to or loading Slack. A separate symptom related to Slack Connect is also occurring where some users are having issues @-mentioning channel members.

We're on the case and will follow up once we know more. We appreciate your patience.
