I’ve been traveling to Poros, Greece and I could not withdraw money from ATMs using my Mastercard Revolut.
I haven’t tried withdraws until now so I can’t say it evere worked in other countries, I will try in Romania in 3 days.
Payments work with no issues at POS with all stores and restaurants.
The ATMs I’ve tried are from Alpha Bank, Piraeus Bank, Euro Bank and a 4th one I don’t remember.
The message from all ATMs is something like “card could not be identified”.
