WEM Shift Schedule Sync Failure in EU-West Architect Context

Stumbled on a weird bug today with the Workforce Engagement Management shift schedule synchronization. The environment is Genesys Cloud EU-West (Paris).

Specific Architect flows triggering high-volume IVR loads cause a ten-minute lag in real-time agent availability updates. This discrepancy impacts the Service Level Agreement calculations in the Performance Dashboard.

The issue persists despite cache clearing and standard restart procedures. No error codes are generated in the system logs.

Can someone clarify the expected latency threshold for WEM data propagation under heavy load conditions?
