WFM Digital Channel Capacity Ignored in Architect Flow

Could someone explain why our WFM publish isn’t updating digital channel capacity in Architect? The schedule publish succeeds via /api/v2/wfm/schedules/publish, but the chat queue depth spikes during the 8 AM CST peak. We’re using a BYOC Edge in Chicago. The flow uses a Set Capacity node linked to the WFM group, yet it seems to cache Monday’s headcount. Here is the flow config:

flow:
 capacity_source: wfm_group
 group_id: "wfm-digital-chi"
 refresh_interval: 300

Is there a known latency issue with WFM-to-Architect sync for messaging channels?
