Client is on v2021 Advanced.  In an appointment with Nuvei/Paya, they were not able to enter Paya Keys in Payment Type Maintenance.  We are working in a test instance of Sage 100.  We disabled EbizCharge in Company Maintenance, but Paya failed to register with a message that the combination of Virtual Terminal ID and Merchant Key were not the correct combination.  At the end of the session, we determined we needed to regroup and find a process by which we can switch the client to Paya without first uninstalling Ebiz.  

Has anyone been through this process and had a successful outcome?  Procedures to share?  We're working our end while the Paya staff person is working his end.

TIA!
