The description is not really clear. Does this mean that my partner can only use one of the subaccounts for 2.99 per month? Also they get a card which can only be used for one free withdrawal per month? What about online cards, how many online cards can the use or share?
If this is the case, how does it replace the old joint account? I can see how this would work for a kid who should only get access to their own subaccount, but I don't really see how this would work in families where partners share finances? The only solution would be to get two premium accounts, which is (quite an) unexpected price increase of 60%.
