Content (please ensure you mask any confidential information):

We're testing the Payables Agent in 26B. We sent an invoice file (PDF) to the Document IO email address. It is currently stuck in status 'Pending Exception Verification' on the Invoice Document Streams page. We cannot find it in the Invoice List, in either None, Policy Violations and Ingestion Exceptions. It's been over 24h and it is still in this status.
