Sunday September 3, 2023

Issue Summary:
From 6:00 PM PST on September 3, 2023 to 12:40 PM PST on September 5, 2023, some users could not launch their Slack desktop apps.

We determined that a code change caused the app to call deleted workspaces for users, resulting in an error and an app loading loop.

Once the root cause was identified, we immediately made an adjustment to the code so that it did not call deleted teams for users, which resulted in the app loading properly once more.

We've resolved the issue that users experienced when connecting to Slack. It is up and running again.

We're sorry for the disruption this brought to your day and we thank you for your patience while we investigated this further.
