We are currently experiencing delays in processing newly logged metrics. As a result, recent metrics from active runs may take longer than usual to appear in charts, dashboards, reports, and API queries. No data is lost. All metrics are being processed and will become visible once the backlog clears. We are actively working to restore normal processing times and will provide updates here.
