I contacted Ubisoft support based on the webpage telling me to do so and this is what happened.
Isaac E: so you haven't entered this on the crews website?
You: No, it says the portal is closed and to upload a picture of my code and links me to chat support
Isaac E: ok you wont like this but i will forward what we were told today
Isaac E: Any player who does not activate the 19 digit Uplay key on The Crew’s website by 11/6 AT 11:59PM, will not be able to do so
You: So then why does it say "IF YOU HAVE NOT HAD A CHANCE TO REDEEM YOUR UBISOFT BETA ACCESS CODE, PLEASE PROVIDE AN IMAGE OF YOUR CODE VIA THE FOLLOWING LINKS:"?
You: What's the point then?
Isaac E: If they miss the deadline for registration, the only option is to register on the waiting list
Isaac E: This is just what we are suppose to tell you guys i am sorry for any incovience
You: Waiting list for another beta?
You: Or for the current one?
Isaac E: current one
Isaac E: but give me a minute and i will get you a code
Isaac indeed give me a code on the spot. So I suggest contacting support and see if you can get a code that way.
