Microsoft account on Switch missing items

Hey there Miss Templar77, have you read this support article about changing the Microsoft account linked to your gamertag?

support.xbox.com/.../switch-gamertag-to-different-microsoft-account

Just tried now and it doesnt work, I tried the workaround via the inbuilt marketplace as per the video but none of my extras show as purchased (it is also asking me to rebuy the warhore, golden guns and other items I also own). It is worth mentioning that
when I follow the link in my profile for undead nightmare collection I get a microsoft error saying "this page has moved"

Are you signing in with the same account on Xbox One and here on the website?

If not, sign in on Xbox One with the account you used to buy the content and you should be able to see it.

If you are using the same account, on the Xbox One, go to My Games & Apps and highlight RDR and press the View button (two overlapping squares) and select Manage Game. Under Ready to Install on this new page, do you see RDR DLC? If so, hit Install All at
the top of the page and it will all begin downloading.

For a visualisation of that last step, finding the DLC for a game, watch this video:

Let us know how you get on.

Yes, I'm singing in with the same account details. Looking at that video it seems like it may solve the issue which I will give a try in a few hours time, I did check the whole manage games tab on the homescreen and everything else but it didnt show, so
this workaround looks like it might work, so thanks for the fresh lead!

Interesting. Thanks for the screenshot! That helps a lot.

We have seen some issues where purchase history isn't showing the full history, however the My Games page is an accurate representation of what you own (minus some newer content, and we're working on getting that resolved).

As Mister Beep said, the issue of it not showing up in the Manage Game section of RDR has been resolved. I'm not really sure why it's not showing up for you in this case. I would suggest a

factory reset, but keeping your games and apps. This is called a console restore, and should trigger your console to realize that the content is there. It will remove your profiles, but your game content should not be touched (saves and such should be fine,
as well).

Let us know how that goes! We for sure want to help you out and make sure the content you own is playable as designed.
