Nordea has a restriction concerning purchases over the Internet. This means that you as a customer needs to reset the UL app, and then re-register your card as you have opened your card for internet purchases on the Nordea internet bank/mobile bank.
You can reset your registration in the UL app by clicking "My Settings" in the menu, and then "Reset the UL app" which will remove your registration. Then you can re-register by tapping "Register pay card" in the menu.
Please note that you will not lose your travel fund when you reset the app and re-register. Your travel fund will reappear after you registered anew, as your travel funds are connected to the phone number that you have stated in the UL app.
