After speaking to my GCS Engineer SMEs, they suggested that they will require proprietary information from you in order to help. Since they need that information, they've asked that I reach out and ask that you open a Support ticket with them.
When you open the Support Case, please reference this PCC post and please let us know the Support Case ID here in this thread so that we may keep track of it for you.
