If you've had a ticket booked using miles cancelled, please let us know whether you got an actual refund.
For the time being, I don't see an option to use a voucher when booking through Miles+Bonus. There is a field for a "Promotional Code" when booking through the regular form (without Miles+Bonus), but this field does not appear when booking through Miles+Bonus.
For bookings with miles (award bookings), when the flight is cancelled by the airline you will have the option of rebooking or a full refund of miles and fees - a voucher is not an option. I can confirm that they do refund, as I had miles and cash refunded for a cancelled booking in March. Also note, according to what
powergean posted earlier, vouchers cannot be used for making award bookings.
Here is one useful thing that I discovered about the 'promotional code' field. On the website 'Book a flight' page, there is no such field on the multi-flight (more options tab). So if you have a open-jaw booking, it is not possible to redeem the voucher. Luckily, the field exists on the app, so it is possible to make a multi-flight booking there.
