So I recently found out that you can use a credit card through Apple Pay to reload Revolut for a small fee (under 1%), similar to Citi PayAll, and this appears not to be charged as a cash advance as it’s blocked on my card.
Not sure if I’ve discovered something as it seems pretty odd that you can easily convert credit card limits to cash so easily.
It was fee free before Dec 2023.
Now only no fee for debit cards.
