Xbox Account sign in and gold sharing problem

You can only share your gold with one xbox one console. However, because the account itself still has gold, as an option, you can share the gold with one console, and play with the gold account on the other. Also, as long as you are logged in to a gold account,
you automatically share the gold, so if you keep the gold account signed in on the unsharing xbox one, it will still effectively share gold.

An account can only be signed into one Xbox One at a time. So if only one account has Gold, only the accounts signed in on that console can share Gold features. The rest will not be able to unless there is a Gold account signed in on the other console.

Are you saying you are trying to share one gold account on both consoles?

Sign your gold account in on your kids console then make that console your 'home console'

This will allow you to share gold with your kids accounts on that console.

Then sign in with your gold profile on your own console and you should be able to play against them

Or have you already done this and are having some other network problem?

For the Xbox 360, there are no sharing features for Xbox Live Gold. Each account will need Gold to go online with the Xbox 360.

It is, however, possible for the both of you to play online (with one paid gold subscription) in "split-screen mode" offered in some games, but only on the same Xbox. One player would need to sign into the Gold-enabled account, and the other would have to
sign into a temporary "Guest" account. You will not be able to go online if one of the signed-in players have "Free" status (non-Gold).

The reverse is true for the Xbox One, though, as it offers plenty of
Gold-sharing features.

Gold Sharing will only work if your Son is signed into your HOME xbox.

If you set your Sons Xbox at school as your accounts Home xbox you should be able to share gold with him however gold sharing on your own xbox would stop working
