I bought tom clanceys rainbow six siege but it says I have to get game pass. What should I do

You do need at least Game Pass Core to play online. So you'd either need to get a subscription or you can refund the game and get a Game Pass subscription that also includes the game.

Tom clancy's rainbow six siege should release a BR mode!!!

I purchased the pre-order of Rainbow Six Siege for xbox one on September 24. As a bonus for pre-ordering this game, I was to receive codes for the two Rainbow Six Vegas games (1 & 2) playable on xbox 360.

I received 2 messages today, one meant for each game. However, the code in both messages were the
exact same, which was for Rainbow Six Vegas 1.

I have no code to redeem for Rainbow Six Vegas 2.

Message 1: "Your pre-order of Tom Clancy's Rainbow Six Siege includes Tom Clancy's Rainbow Six Vegas for Xbox 360 (ESRB Rating: MATURE with Violence). Redeem on Xbox 360 or Xbox.com/redeemcode"

Message 2: "Your pre-order of Tom Clancy's Rainbow Six Siege includes Tom Clancy's Rainbow Six Vegas 2 for Xbox 360 (ESRB Rating: MATURE with Violence). Redeem on Xbox 360 or Xbox.com/redeemcode"

Can anyone help? I´ve bought Tom Clancy's Rainbow Six Siege Season Pass for Xbox One [Digital Code] online. I´ve redeemed it trough Xbox.com but it doesn´t show on my Xbox one live account?
