Trying to understand why agents are getting dropped from the IVR menu when they approve a shift swap in the WFM app. The Architect flow uses a standard queue node, but the session terminates with a 408 Request Timeout right after the swap confirms. Is there a known conflict between the WFM self-service webhook and active IVR sessions? Checking the integration docs but nothing specific pops up. Chicago team needs this fixed for the morning rush.
