My partner and I have been using a digital Two Together railcard for a couple of years without problem. Each of us has the card on the Railcard app stored on our Android phones. The app is up to date; no updates are pending. Last week, an Avanti train manager told us our railcard was invalid because it was not displaying a QR code. It never has. It simply displays a numeric code on the bottom left of the photo-id screen. He said he would overlook it this once, but that we must contact Railcard to get our apps fixed. I presume this is nonsense?
