It looks as though the implementation will not inherit flows for config or report definition from pegaca it is in the inhertance path however.
Building a flow in our SS implementation allowed it to be selected in queue config but it would not allow simple questions directly. I put a conversation flow inside the new flow and that allowed either flow to be selected. We selected the inner flow directly.
Self Service implementation is built on Pega Self-service and Customer Service implementation is built on Pega customer service. We have 8.7.1 for both platform and customer service.
