Hi @kevmuko,

We have released a new PQS version that fixes the issue you observed: [PQS interface view bug and deployment model change in Canton 3.4](https://discuss.daml.com/t/pqs-interface-view-bug-and-deployment-model-change-in-canton-3-4/8448) . Hopefully, this solves the problem for you as well.
