Sometimes when u buy it, it may not have downloaded. Go to the store ingame, go to expansions and make sure that there is a check mark on all the expansions u have. If so, select it to make sure there isn't an additional download waiting. If ur still having trouble then I would try contacting bungie about ur purchase or wait for them to respond here if they do. Hope this helped.

Hey, Can you verify that the Microsoft says that you own the expansion? Microsoft did not initially charge people for the bundle however still gave them access to the content, if there was a problem with a payment then they would of revoked the license. However if Xbox says you do own the expansion then you can try [url=https://help.bungie.net/hc/en-us/articles/360049196071-Accessing-and-Restoring-Licenses-to-Destiny-Content]Restoring the Game License[/url] as this can help with situations like this. However if this does not work you will need to contact [url=https://support.xbox.com/en-US/contact-us]Xbox Support[/url] as they are the ones that control the allocation and management of DLC. Bungie does not have any authority over this and wont be able to assist.
