I thought it’s only on your ST if it’s the original seat? If you buy another you get a e ticket , any way easy way around it is just to download the Spurs app as the ticket will be in there so just use that if can’t get the cardOriginal message on website said if you bought a Ticket other than your ST seat you would need an e ticket.
Now saying all ST holders are having it on their card. We had a panic up cos my mate didn’t have an e ticket, just his card when he moved seat.
