Performance Dashboard Lag in EU-West Architect Flows

Can anyone clarify the synchronization delay between Architect flow completion and Performance Dashboard updates in EU-West? The delay currently exceeds forty-five minutes for high-volume queues.

This latency prevents real-time monitoring of abandonment rates during peak business hours in Paris. Standard cache invalidation procedures have been attempted without success.

Is this a known regional infrastructure constraint or a configuration error within the tenant settings?
