Digital Channel Conversation Duration Metric Discrepancy in Performance Dashboard

Could someone clarify why the Average Handle Time for digital channels in the Performance Dashboard consistently registers at zero for completed interactions? Our EU-West BYOC environment is routing inbound webchat sessions through a standard Architect flow with no custom scripting delays, yet the historical reports show valid duration data while the real-time performance view fails to capture the metric for agents currently in status. This discrepancy is preventing the operations team from accurately monitoring digital agent efficiency during peak hours.
