Daniel FYI: That feature got added in Early 2020 and then got removed again a few weeks later because of issues regarding the liability shift for payments: https://together.bunq.com/d/25824 As far as I can see, top-ups via Apple Pay actually work again now, probably because it's easier to protect from fraud against users that have gone through identity verification. Unclear if this will ever come back to public bunq.me pages and requests, but there haven't been any other updates since then.
Of course, would be a nice feature for all honest users :)
