Quick question about Predictive Routing alignment with WFM Schedule Groups

Quick question about predictive routing capacity limits. Our outbound campaign keeps stalling with 503 Service Unavailable errors even though the BYOC trunks show healthy status. I suspect the issue lies in the schedule_group_id mapping within the campaign settings. We updated the concurrency_limits in the WFM schedule group last week, but the predictive capacity doesn’t seem to reflect those changes. Is there a specific API endpoint to validate the link between the campaign and the WFM group? Using Genesys Cloud v2023.10.
