Yes, the previously closed card has disappeared from the list now... which is good to see..
Probably they don't want customers to see the old.cards and ask for transfer of CL from the old card to existing cards .. Anyway good move
I closed 2 SBI cards couple of months ago, 1 of them was earlier appearing in the app and is still appearing and infact I received reward points on this card after closure
2nd card which was not appearing on app started appearing on the app after closure
