BYOC Trunk Audit Log Latency for Credential Rotation in AP-SE-2

Can anyone explain why the Admin UI audit trail shows a 15-minute delay for credentialRotation events on our fifteen BYOC trunks in AP-SE-2? The API logs via /api/v2/trunks reflect changes immediately, but compliance requires synchronous audit visibility. This latency breaks our automated security reporting pipeline. Does this affect only the AP-SE-2 region, or is it a global limitation for bulk credential updates on BYOC configurations?
