Game Pass ultimate and sharing with a child

Will this feature be available for the child account eventually? The account has its own active game pass ultimate. It is not using game share off the parent account, which does not have game pass of any type.

I have the same type question. My daughter got a gaming PC for Christmas. We have xbox game pass ultimate. The subscription is in my husbands name and my daughter plays under my name. I can sign her into the computer under my husbands name and download
the games, but for games that offer online parties (especially ones that don't offer couch/split screen) I would like to play with her, me using the xbox and her on her computer. However, when I try to do this, I cannot invite her to the game. Can someone
walk me through, if this is possible, who has to be signed on where? It acts like we both have to be signed on as my husband or I can't access the games on the computer, and then we can't play together because we send the invite to our self? Our xbox is
already set to the home xbox. What am I doing wrong?

You need to set the console as your Home in order to share with him. https://support.xbox.com/en-US/help/hardware-network/console/my-home-xbox

On PC, even if Xbox Game Pass Ultimate there is no option to share it yet but if you're pertaining to Xbox console, yes, you can share Xbox Game Pass Ultimate.

As others noted, your children need an active Gold membership subscription to be able to play online multiplayer (other than free to play titles like Apex or Fortnite).

Since you say the child can play online multiplayer when you are signed in on that console, I assume your own account has an active Gold or Game Pass ULTIMATE subscription.

In order to save some costs, you can do the following:

Give one child (let's call it Child A) a gold membership subscription or a Game Pass ULTIMATE subscription (a "regular" Game Pass subscription won't do it).

Now Child A goes to the console of Child B and sets that console as their own Home Console in the settings of the Child B console.

Now the Child B console shares the Gold membership subscription with ANYONE playing on that Child B console.

As Child A is the owner of the Gold subscription, they in turn can go to ANY CONSOLE and their Gold subscription goes with them.

So Child B can play Minecraft online Multiplayer thanks to the shared Gold subscription on the B-console, and Child A can play on their own console (or any other console) thanks to the Gold membership on their Child A account.

If you yourself don't play online multiplayer, you can then cancel the Gold subscription on your own account, and the kids can play with their own accounts.
