Unable to make an online payment

Which website/ merchant?
Within Europe and especially Romania* revolut might fain online due to lack of 3D secure which is mandatory.

*as I tested, merchants which uses LibraBank, Netopia MobilPay and few others don’t accept any card which doesn’t have 3D secure (iaBilet.ro, autogari.ro, my hosting company)

Also it doesn’t work on other websites. Like instant gaming, Kinguin, due to the same reason. But they have more payment options.
