Predictive routing dashboard freezes on pacing slider at 1.7x multiplier

The predictive routing dashboard just freezes on the pacing slider the second the campaign tries to sync with the eastern callable window. Admin UI throws a 422 UNPROCESSABLE_ENTITY on POST /api/v2/outbound/campaigns/{id}/settings when the multiplier hits 1.7x. Console logs show the request payload gets rejected for a DNC compliance mismatch, but the contact list was scrubbed yesterday. Predictive mode starts dropping calls into the progressive queue without any warning.

Environment sits on Genesys Cloud 2024-03-EDITION with the latest admin UI patch. It’s throwing that abandonment cap at 3.2% instead of the configured 2.5% threshold. Cache wipes do jack all. UI just spins and won’t budge. Multiplier sticks at 1.7x and the outbound pacing graph flatlines. Network tab shows the settings payload keeps retrying every 4 seconds until it times out with that same 422.
