Specialization Code - Invalid

Hey there,

So I just got around to obtaining the 6 extra specializations, but when I enter it the code it comes up as invalid. I was wondering if I had to enter it in before a certain time or whatever? I haven’t claimed it yet nor have I typed it incorrectly. Any help is great.
Thanks!

Im glad to see you got a code. I have the limited edition and never received a code to unlock the other specializations. All I have is Wetwork and Operator and I have a bunch of Double XP and can level anymore. I checked my email and never got an email for the codes to unlock them.
