Summary

Between Thursday, July 10, 2025, at around 9:36 AM PDT and Tuesday, July 15, 2025, at around 2:50 PM PDT, some users were unable to accept email invitations to join workspaces. This affected newly invited users to a workspace.

A recent feature toggle, intended to adjust a backend validation system, was enabled for a small subset of users. This introduced an unexpected mismatch that prevented the "Continue" button from functioning properly, leaving it in a non-actionable state.

We rolled back the feature toggle, resolving the issue for all affected users. Workspace invites sent via email now have an actionable "Continue" button.

Resolved

This issue is now resolved for all users.

• Current status and actions being taken: We identified and reverted a recent change that caused the issue. Invited users should no longer experience issues with accepting new invites to workspaces in Slack.

Thank you for your patience as we worked on resolving this issue. We apologize for how this may have affected you.

Update

Our work on this issue is still ongoing.

• Current status and actions being taken: Invited users may still encounter trouble accepting their invite to the workspace as the "Continue" button is not actionable.

We'll be back with another update once we have news to share.

2:51 PM PST

Investigating

We're investigating a new incident.

• Current impact to end users: New users are experiencing trouble accepting new invites to workspaces in Slack, resulting in a greyed-out button that prevents the new user account from being created.

Thank you for your patience, and we will be back once we have a significant update.
