Apparently it depends on the country you set up your PayPal account in (unlikely to work for you). Even if (Transfer)Wise now supports direct debit and they say you can easily do it, still often does not work, even for Europeans (e.g. me) when trying to link the account to the Wallet. It did recently work with the card though. See also people thinking it shouldn't work, people making it work regardlessly and effortlessly, etc
