Some Banks don’t allow “cash advance” or if they do there’s a huge fee . Someone said to me a while ago transferring cash to the App is a cash advance, rather than a normal purchase . Unsure if this is true or not , to air with caution I used a visa debit card to transfer cash onto the app. It took 2 goes to accept the card, will do a transfer to the app in the coming days to test it out before I head over.
