I downloaded the Season Pass on May 31st on my 360, that way I could get Ghosts DLC on both consoles. On my Xbox One, it's showing that I have the Season Pass activated and that I have Onslaught/Devastation downloaded to my HDD, but none of the maps show up in matchmaking playlists or in private matches. Under the private matches setting, when I go to choose, "Bonus Maps" it says I don't have any and asks if I'd like to purchase them in the store. When I'm in the store, the Season Pass has a checkmark indicating I own it but the map packs do not. When I click on them a note pops up saying I have them downloaded to my console already, which I do. I tried uninstalling them and re-installing but that didn't solve the issue.
I'm not sure if I'm not doing something right or if it's just not recognizing my season pass membership. Any and all help would be greatly appreciated regarding this matter.
Might have to do a license transfer. Same thing happened to me and that's what I had to do. Whenever I tried to play offline I couldn't use any DLC. Make sure your Xbox is set as your primary console as well.
