I can no longer access game library on my recently donated One X. I was previously able to...

I recently purchased an Xbox Series X, I game share with a friend and assumed we had to do all the Home Xbox stuff again.
I added his account and made my Series X his Home Xbox and he added my account and made his Xbox my Home Xbox.

However, he has access to both of our libraries whereas I only have access to just my library and we have no clue as to why this is.
He then removed my account and tried again and still Game Sharing isn't working.

Unsure if its a bug/issue with the Series X or not but another friend of mine got an Series X and hasn't had issues with Game Sharing with his brother.

I'd appreciate some help with this, I'll be visiting my friend soon who I'm Game Sharing with to see if it was done correctly or not.

For what it’s worth, I have the exact same issue as you described, even down to my friend having access to my library but not the other way around. This issue has only started very recently as well.

Yes, I've gone to the website to download X Box One games to my library, but I cannot.

To clarify again, I don't have an X Box One console so I cannot install it. The message will say I don't have the required device.

I do have a one year gold membership, pre-paid card.

In the past, games with gold can allow me to add an X Box One game to my library even without an X Box One console. If I purchase an X Box One console, my free games with gold games will be in the library.

Now there is no option online to add the X Box One game to add to the account unless I own a X Box One console.

Hopefully, you can help further. If not, thanks for the reply anyways.

Yes I know the game no longer receives updates and I was able to play it the other day but all of the sudden the full game is no longer in my library same for bedrock edition.

You can only have 1 console set as your Home at a time. So if the Series X is set as the Home console, you will no longer be able to access the games on the One without the account that purchased the games.

I was able to find all previously installed games in Xbox library, installation has started

Thanks for your help
