Unable to remove boarding passes from wallet
I have 2 tigerair boarding passes in my wallet which I can't remove. There is no option from within settings/wallet & apple pay to remove these as they are not showing. There was also no option within the Tigerair app and I have since deleted the app and the boarding passes are still there.
I have removed all cards in my wallet and the boarding passes do not show up but as soon as I add a card again the boarding passes are back.
Does anyone have any suggestions?
