This is all a bit mind boggling. There’s no sign of my 60+ card in the Oyster app or on the Oyster web site. I logged in to my photocard account and it showed a 12 digit number (that is not printed on the card) but when I tried to add that on the app it said it’s registered to someone else!
The Oyster app has the corresponding 12 digit no, but says the card is first gen and so won’t work. The card had the “D” on it, which I understood to mean that it’s not first gen.
