You have right, I was not explain correctly, but the card sometime work in pounds and other in euros depending if you are operating an ATM or you are shopping with it.
Really the charge at ATM was in pounds instead euros, however when I bought in shops, restaurants and others, these was in euros. Here the screenshots I posted in other threads for better understanding.
If you can see in both, At ATM image say 53.31 at final charge was 56,35. These are pounds not euros. We can see that Revolut apply a second exchange with no charge on it.
The issue with DCC also happen in euros. In shops, restaurants and other, DCC was applied too without advice me.
At receipts on Revolut app we can see:
We can see the operation was in pounds. It have arround 3 pounds of charge with no notification during withdrawal operation at ATM.
So the DCC must be an option at Revolut app to decline it by default.
The first 6 numbers of the card are 527346
