I asked this question in the Ubisoft forums yesterday

So from this reply it would seem that I still have the limit of 30th November
I bought a RTX 3080 yesterday and for obvious reasons all I could get was a pre order, OCUK can't give me a date when the card will be delivered. WD Legion is free with the card but is there a cut off date as to when it can be claimed. If my card arrives after that date, do I lose the abilty to claim the game for free?
