We are currently experiencing issues where some customers are unable to log in to the Siteimprove platform using SSO via siteimprove.com and my2.siteimprove.com. Impact: - Users who are already logged in should not experience disruption unless they log out or their session times out. - New login attempts may fail. Our Development Team is actively working to identify the root cause and resolve the issue as quickly as possible. We apologize for this inconvenience. We'll continue to keep you updated.
