I actually had some issues with my old Revolut Mastercard with TfL. I asked them to check whether this was the case also with others, but no answer. I let this slip as I have plenty of other cards, but still.

After a couple of months, they acknowledged the issue and provided me a free new Revolut Visa. It still took about 2 months to get it in my hands, after having sent a couple of messages via Twitter.
