We have successfully addressed the root cause of the login failures. Authentication for both the Process Designer and Process Navigator is fully stable, and all customers can now log in. Some users may experience a slightly slower initial response time upon their first login, which will resolve itself immediately after. If you continue to see any persistent errors, please clear your browser cache or reach out to our support team.
