Latest update from Smartsheet

Approximately on 3:15AM Pacific Standard Time February 22nd, 2026 in our Australia region, a deployment was performed to resolve a performance issue. However, a configuration required to validate session cookies was incorrectly specified, which caused the web app to become inaccessible after successful login. The issue was mitigated within 80 minutes by toggling a feature flag to reroute traffic back to a stable service and full functionality was restored by 4:35AM Pacific Standard Time February 22nd, 2026.
