CXone v2 Reporting API: Real-time queue stats returning stale data

Trying to pull live queue stats for our Manila team using the v2 Reporting API. We need second-by-second updates for a dashboard, but the data seems lagged by minutes. Here’s the call:

GET /api/v2/analytics/queues/realtime

We’re passing groupIds and metricTypes. The response is 200 OK, but the intervalStart doesn’t match current time. Is there a specific parameter for true real-time streaming, or are we missing a config setting?
