Dragon Age Origins Xbox No DLC

I'm having this issue as well. I tried to file a complaint through the help center, and they don't even have X-box One listed as a console, so I can't even file a complaint properly. Is EA just not supporting this game on consoles at all anymore?

EDIT: After a lot of beating my head against the controller, I figured it out. It's an issue with both the servers being down for DAO as well as 360 compatibly not being as great as it could be for X-box One. Because the servers don't exist for the game anymore, X-box doesn't know to download your DLC when you get the big pack, so it just... doesn't. You have to tell it to download it manually.  

Go to your game library and highlight DAO, then press the Options button. Select "Manage Game and Add-Ons" from the window that pops up, then select the game itself. It should take you to a screen with the game, and a list of all the add-ons you have attached to it. Select each one you want to download, and select save changes. Wait until they all download, and then boot up the game. 

Sadly, this will ONLY work for DLC that is still supported by EA and X-box. If it's not supported anymore, then it's lost for good.
