On Reddit, several people report that there are problems with the refunds - either with the tickets (only partial refunds are confirmed) or with seat reservations ( a refund of the reservation fees is denied). The whole process does not seem to be that straightforward.
Currently I am not sure whether I should submit the refund form for a flight on March, 13 which is still shown as active or better wait for the cancellation of the flight. A cancellation by Emirates would probably provide better refund chances.
