I'm working with a new Mini 3 Dev Kit trying to setup semi integration with Cloud REST Pay Display.
I have successfully been able to ping the device, display messages, and print receipts. However, I receive this error trying to initiate a payment:
{ "code": "processing_error", "message": "Unable to start secure payments : ", "requestId": "547919e5-8505", "requestType": "PAY", "type": "api_error" }
On the device if I go to Setup (DEV) > Payments > Device Status it says "Card payments are not allowed on this device".
If I go into the Sale app and try to charge something, it says "Payment app not found"
How can I resolve this problem so that I can continue my work on semi integration?
