I cannot use my Xbox live from my home Xbox which has game pass ultimate

There is plenty of information suggesting both Game Pass Ultimate and Xbox Live Gold are shareable on a machine designated as the 'Home Xbox'. The below information is from the Xbox support information.

I have an Ultimate subscription and my Xbox is set as my home machine. My son is simply logging in to his profile on that same Xbox and has access to games I have downloaded on my side, but if he goes in to Live Gold on his side its asking him to subscribe and not allowing him to use my Gold subscription as suggested.

Can I share Xbox Game Pass Ultimate on my Home Xbox?

Yes, standard Xbox home sharing policies apply for both Xbox Game Pass and Xbox Live Gold. If you have an Ultimate subscription and have designated your home Xbox, you’ll automatically share your subscription with any profile signed in on that console.

Sharing your Xbox Live Gold subscription

Here’s how Xbox Live Gold subscribers can extend their Gold subscription benefits to friends and family.

At home: Make your primary Xbox (if you have more than one) your home Xbox, which gives anyone who signs in to the console with their profile the ability to use your Gold subscription.

I have Xbox Gold and Game Pass Ultimate on my designated home console. When my friend signs it to her account on my console. She cannot access my Xbox Live gold or Game Pass Ultimate. How can i share these subscriptions?

Game sharing is only allowed with in households

The Rewards program rotates out some cards every now and then. They usually return though.

The Rewards programme has not rotated the Xbox Live Gold pass nor the Xbox Game Pass Ultimate, both of which are useless when one does not have an Xbox. This is discrimination against PC gamers, which is appalling from Microsoft!

In addition, I recently used rewards points for an Xbox Live Gold pass, thinking naively that it could extend my Xbox Game Pass for PC. It didn't but created a useless additional pass that I cannot use.

I asked the Microsoft Rewards support team to cancel the pass and reverse the Rewards points redemption. Of course, they did not do it – and cannot be bothered to provide any feedback. Appalling customer service from Microsoft.

No, you cannot use your game pass ultimate on 3 Xbox consoles at the same time. For starters, you cannot log in on the same account on multiple Xbox consoles at the same time.

What you can do is share your game pass ultimate subscription on one console, by setting that console as the home Xbox. Once you have done that, then anyone using the Home Xbox can access the game pass ultimate subscription without having to log in with
the account that has the subscription.

You can still log in with the account that has the subscription and play your games and access gold as much as you want on any Xbox, and your son can use his account on the home Xbox and access the subscription on there.
