Was the device code that you used to pair the Terminal created by CreateDeviceCode? :slightly_smiling_face:

I am running into the same issue, any luck with fixing this?

SDCo - I assume you are using the Terminal API. So you cannot log into the Terminal with your account, you must use the CreateDeviceCode API then log into the Terminal with the Code provided in the API response. In order to switch the account, simply hold in the power button and reset the terminal then on reboot it will prompt for log in and use code.
