So due to the server loads and errors during the Ubisoft Forward event. Many people were not able to obtain the rewards for logging on during the live stream.
However, later not only did Ubisoft acknowledge the issues…they made a statement that EVERYONE could receive the rewards at a later time due to the issues. This was regardless of you watched the stream or not.
SO…to do so…go to their website, which I have linked, and you enter your account information and select your gaming platform. Ubisoft will then add the title/rewards to your account.
