New ST App, Arduino Thingshield, Vista 20P Integration Issues

Ok, so I had AD2SmartThings Arduino Thingsheild, Alert Handler 2.3 setup on my old ST app which is still working. However in the new App, while I can see the state of contact sensors via alarm panel, I no longer have the custom UI controls in the Arduino Thingshield device. I just have an on/off button which controls just the chime. The Stay/Home/Away controls on the new app are also not controlling the alarm panel. Where do I start in fixing this integration with the new app?
