We have successfully deployed the fix to production and the issue is resolved.
The Admin SSO and Authentication Configuration page for standalone workspaces should now display the correct settings. If you continue to see outdated information, refresh the SSO Admin page to load the latest changes.
update
We have identified the trigger and developed a fix. We are currently deploying this fix and expect to resolve the issue shortly. We will provide another update once the deployment is complete.

update
Some workspace admins on standalone (non-Enterprise Grid) workspaces may be experiencing an issue where the SSO and authentication configuration page does not display current settings as expected. Admins may see a blank value for the "Require SSO authentication for" field on the admin SSO settings page, which does not accurately reflect the actual backend configuration — SSO settings remain intact and in effect.
We are actively investigating this issue and will provide an update as soon as we have more information to share. We apologize for the inconvenience.
This issue is now resolved for all users.
We apologize for any disruptions to your day.
update
Some users may be experiencing issues performing certain actions in Slack, channel creation, invitation, and join operations may result in a degraded experience. Thank you for your patience while we continue to investigate the situation.
