   We are currently investigating an issue affecting Cognite Maintain for OMV Romania Asset Oil in Production. Users with edit rights are unable to update an activity date, create duplicates, or run deferment calculations. Browsing and read actions continue to work normally. All other customers and clusters are unaffected. Our engineering team is actively investigating the root cause and will provide further updates as soon as possible

   We identified and fixed an issue affecting Cognite Maintain for OMV Petrom Romania (Asset Oil) where users with edit access could not update activity dates, duplicate activities, or run deferment calculations in production. Read-only access was not affected. The fix has been applied and the service is operating normally. Root cause: Expired application client secrets on the backend authentication path caused write operations to return 401 Unauthorized in production only. Resolution: New client secrets were generated and applied. The service is operating normally as of Jul 15, 2026, 1:10pm UTC.
