@rixx My confusion is probably based on what people said when the first vouchers were sent out before reading it myself. The (current) state of the text is actually quite okay tbf.
If you append something like "It takes at least 48h for a voucher to replicate" to that FAQ it should be very clear and you don't have to think about the details that much.
Nitpicking now, but the page says 24h old and *older than* 24h further down. Might add to confusion, although not technically relevant.
