Halo Infinite Flight Steam Key already used

As the title says, I went to paste the key given to me to activate on Steam and it tells me that the key has already been used. I know it’s been addressed on Twitter, but I’m posting this hoping someone will see it?

A moderator mentioned to submit a ticket if you are having this issue in the official blog, however when I submitted a ticket it i got this: Halo Support is unable to create new flight invitations or modify existing invitations.

So Hopefully it actually gets resolved, but I doubt it.

There was an issue with duplicate/invalid Steam keys earlier, resulting in codes having to be re-generated and published a few times. 343 have resolved this issue now and distributed new and working codes to everyone affected. If for any reason your new code still does not work, please file a support ticket on the Insider Support Site.
