Thanks Steve. I'm a bit puzzled by all of this. We've bought SCA on the basis that it supports 3DS 2.0. Cybersource are Netsuite's preferred payment partner. If 3DS2 doesn't work with them, who does it work with? There's a deadline to have this in place in October, which is going to be mandatory for UK customers. I'm sure the same applies EU wide, but it may even be a global issue. I've got a case open regarding it, but I'm not getting a straight answer at the moment.
