Sorry to say, this is incorrect information.
I have a few credit cards which doesn’t show anything in dreamfolks portal (error: not eligible for digital access) but they have valid lounge access both domestic and international. Those are not on Amex or Diners. Mostly RuPay cards, but the same is happening for my YES MARQUEE card as well… which is issued on visa network but they have a tie up with Loungkey… hence it doesn’t show up
