Just noticed that the audit logs for our ap-southeast-1 BYOC trunks are stripping the SIP registration credentials from the change history events, which breaks our PCI-DSS compliance reporting. The GET /api/v2/architect/flows endpoint returns the flow definition but the historical state changes lack the masked credential hashes we need for the quarterly review. Is this a regional limitation in the Singapore cluster or a bug in the current Genesys Cloud release?
