Updates from Slack 3
- 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.
