I did the code registration, including creating an account on Ubisoft. I received an activation confirmation in the email.
"Thank you for redeeming your code for Assassin’s Creed Valhalla PC Standard Edition on PC.
You will receive your unlock instructions via e-mail at game launch. "

How do I proceed now?
I haven't received any emails and the code is no longer working.
The game does not appear in my account.

Thank you for your answer and, if necessary, advice on how to deal with it now.
