  1. resolved Dec 17, 2024, 10:26 PM UTC

    On December 17, some Sigma users encountered column errors—such as "Reference to errored column" and "Expression contains errors"—when loading visualizations and tables. This issue surfaced as a result of introducing a workbook performance enhancement to the product. The issue has been resolved by reverting the recent change, and the Sigma application is now fully operational. We will conduct a thorough root cause analysis and share a detailed postmortem in the Sigma Community in the coming days. Incident Start Time: 15:49 UTC Incident End Time: 16:55 UTC
