Summary: Customers experienced an inability to upload and link files to Checklist Items within the Close Optimization product.
Root Cause: The incident was caused by a code regression introduced during a scheduled release designed to optimize system performance. Specific changes intended to improve application responsiveness inadvertently disabled the trigger mechanism required to send files to the backend system.
Immediate Resolution: The engineering team identified the problematic update and restored proper functionality by reverting the application to the previous stable version. The fix was validated across all production environments to ensure the file upload capability was fully operational.
Follow-up Actions: To prevent recurrence, the team has implemented new automated end-to-end testing specifically for the file upload workflow to catch similar issues prior to deployment. Additionally, the performance optimization code has been removed from the main codebase for further review and correction before future re-release.
