After a bit of a rough start, Microsoft has corrected an issue preventing some Xbox One owners from redeeming their code for Call of Duty: Black Ops 3's beta.
Great news! Issues redeeming Black Ops 3 beta codes should now be fixed. Let us know if we missed your Tweet & you still have questions.

The multiplayer beta began on Tuesday for Xbox One and PC, but users were unable to redeem the codes, preventing them from downloading the game. With that fixed, the beta should now proceed as normal, although Treyarch has acknowledged theya re looking into a "freezing issue."
Thank you for your patience while this was resolved! We’ll update you on the freezing issue…stand by. https://t.co/P6MHBz5FVY

There was no mention if the beta will be extended due to the problems experienced, although Treyarch did extend the PS4 beta by a day so it is possible they will do the same on Xbox.
