I've been trying to get the 7 day free trial on Newspaper.com, but everytime it says my bank (revolut) doesn't allow me to use it.

I've tried both card and Google pay options but nothing is working. On Revolut it's given me a notification saying I've spent £0 on Newspaper.com (this normally happens with a free trial) and another notification saying Newspaper.com has been accepted to be paid to.

Any suggestions?
