When looking at the home / accounts page at the various Cash Balances it’s kind of weird that Cash stored in Vaults is not visible there. In fact the only way I can find out how much USD or GBP I’ve got is to go to Wealth/Vaults and write down the totals, then add them mentally to totals displayed on the Accounts page!
SUGGESTION: somehow include the vault totals on the Accounts List of the Home Page of the App. Perhaps by putting the total of the GBP vaults next to the total of the GBP accounts, but in a different colour. And then giving the grand total at the top to reflect the total cash that the user has with Revolut.
