The same thing happened, I bought the digital version and the game pass is not appearing. I downloaded the classified zombie map but no result. please correct this problem.
I found a solution for Xbox one. Go on to the Xbox store go on to the black ops pass and on the top right it should say press X to install and if you press X it will re install and hopefully work.
I have been having this problem too.
Don't feel bad. I just purchase the season pass last night and downloaded it. Today they want me to buy it AGAIN Probably a glitch or something that will be fixed Soon?
Has anyone had luck with refunds from Microsoft or Activison if they were forced the re-buy the pass?
