QR scan system is unusable

The new QR code system is terrible. It took me 4 attempts to get my details accepted and I left 3 people still battling to submit details. The manager of the store said they were going to stop the service as they do not have the time or the staff to try to deal with all of the complaints and problems. I checked the delivery details online after finally being able to submit and Address line 2 was missing. Is this a problem with the display or did that line not submit? It is crucial to the delivery so needs to be there. This would never have happened with the paper based waybill.
