Mastercard for me 539123 bins
I seem to have discovered something, Uber with a Revolut Card will not work on ios
To test i had an ios 11 device with an austrian acc. and card was declined even though tried as i got the Uber Bv authourisation message.
Moving to my android phones.
Romanian acc. And austrian took my revolut card as my only card.
Tl;dr: ios bad, android good
