@Ubi-Keo Yea I accidentally made my original posts with the wrong account haha. The account I use to play the game is @TheBigJA

@Ubi-LadyBlue
Thanks for getting back to me on this. I am on the same Microsoft account as the one that bought both the game and DLC. I am not game sharing with anyone either. The only thing that is "different" is that I am now at college and my Xbox Series S is here with me instead of back home. I have an Xbox One back at home that I originally bought the game on and played the game on for a while. However, there was a period of time after I upgraded to the Series S that I also played AC Valhalla and my add-ons were there at the time. I was able to access and play them on both the Xbox One and Series S. Both Xbox are under the same Microsoft account. My Series S is set as My Home Xbox. Now they are unavailable obviously hence my predicament. I do not think this should make any difference right? Especially since I have the Series S set as my home Xbox.

@Ubi-Perseids Here is the screenshots of all my downloaded content

@Ubi-Perseids Here are images of the messages the game has shown me. I will also upload pictures of my content installed shortly.
I tried the troubleshooting methods on your provided links and I have either done those things already or it didn't solve my issue.

@FeliciaFinesse I do have a manual save and that is one of the ones that says it is not up to date which is strange because I would assume it is saved to my xbox itself and not binded to an IP address. The manual, auto, and cloud saves all show the same message. Going through the pause menu to the Animus store shows that everything should be downloaded. I just got the message that Dawn of Rangarok entitlement is detected but the quest doesn't come up either which may be another issue on its own haha.

Hey, I am on Xbox Series S and am having this exact same problem with Wrath of the Druids, Siege of Paris, and Dawn of Ragnarok. The game isn't recognizing any of it. I also have the season pass so I am not sure if it a season pass issue. I have tried all of the fixes in this discussion and subsequent ones I have found and still no luck. Is there anything else I can do. I just bought the Dawn of Ragnarok DLC and would like to play it. I just constantly get the "Missing Add-Ons" message and then the one that says "New downloadable content has been detected. You must return to the title screen to access it. Do you want to return now?" I constantly get that message and no matter what I do, nothing is working. Any help would be appreciated. Thanks

For context, I am on Xbox series S so my game is all digitally installed. The content I should be able to access from the Season Pass in AC Valhalla is not working. Everytime I open the game up it says that new content is available and my saves are out of date. It did not use to be like this. For example, I already have completely completed The Wrath of the Druids but now it claims it isn’t there. I moved to college for the and now all my additional DLC content is not there. I am trying to start the Siege of Paris but the content is not there. I have everything downloaded to my Xbox so that isn’t the issue. I also just bought the new dlc Wrath of Ragnarok and I’m not sure that’s appearing either. I have tried uninstalling and reinstalling a handful of times along with moving back and forth from external drive. Nothing is working. It’s just like the game isn’t recognizing it’s there. Does anyone know a solution to this? Any and all help is much appreciated. Thanks.
