I use it regularly in XP12. Weight and Balance is Fuel only, no Passenger or Cargo. There are a few Bugs (no Lights for the selected COM, Right Push Button on G500 Inop) that annoy me but Flight Performance seems pretty close within the Limits of the SIM. I use the Classic Cockpit Version without the Radar.
I hope there will be a Fix. Maybe one Reason is the Status of XP12 with it's fast changes in short Time that could be a Nightmare if you are the one and only Developer for a Project. Latest announcement from the Developer was, that he was working on this and some Performance Updates. But that he needs Time for Testing and his Time is limited because of other Projects.
But a short sign of Life would be nice. And maybe a small Fix for the COM Lights and the Push Button.
