Is it best to transfer GBP to Euro in the app before travelling from the UK to Europe or does Revolut automatically do the GBP to Euro transaction each time you make a payment or withdraw euros?
The app does it automatically but be aware you will get a poorer rate at weekend.
You can avoid this, or fix the rate by buying euros ahead.
You should also read the help section regarding how payments are taken and from which account.
Thanks for that @TonyP I’ll exchange to euro’s ahead of the weekend trip.
