If you receive An unexpected error occurred this is most likely an issue with the gateway. We have found that this can occur when there are new terminal builds to be pushed.
Please confirm terminal builds with your gateway first.

If you are unable to use the payment buttons (the payment buttons appear inactive or deactivated) it is because the gateway has not been set up correctly or you have deactivated certain payment flows from the POS+ portal. Please confirm the setup to proceed.
