“Account is not authorized to play halo infinite”

I was playing halo infinite yesterday with my friends and then when i tried to get on today it says “your account is not authorized to play halo infinite” even though i yave the invite

Same here, but I did my research and it appears like it is something on their end, not with the gamertag or key.
I’m on PC, but if you’re on Xbox just make sure that all other users are logged off, making sure that the user with the gamertag allow to play Halo Infinite is the only one logged in at the moment of playing, try restarting the console too. They are working on it to fix it, it happened on the first flight too. Try logging in until the game allows you to play, you may be on a queue waiting to join the servers to be able to play the game.

i was on xbox and i fixed it by just signing out and back in
