Be aware that I believe they have some sort of currency pinning to the country that you opened the account in. I opened mine when I was in Ireland, and when using it in the UK occasionally I see € amounts in the app (usually notifications), even though I haven't used it in a € country for a few years. I've also seen my balance varying in £, even though I've only topped up in £. I'm not a heavy user so I haven't dug into it too much (and the rewards make up for the odd penny here and there).
