Is cancellation the only option?

i see where there is the issue, you have an xbox with ultimate on your account set as home, this means your child can then play the games on his account, on pc, gameshare like that does not work so he needs his own subscription on the pc.

best thing to do is just buy gamepass pc via xbox pre paid cards from gaming retails stores or cd keys.

or when the sub runs out on console, get him to set his account as home and purchase a prepaid ultimate sub as above, then anyone on the console gets to use the perks and he can then use xcloud and gamepass on pc without issue.

I did check, the Xbox does have both accounts on it and I have it marked as my home Xbox. I unchecked and selected again to see if this wakes up the connection.

On my son's computer, it says he cannot purchase and it cannot send a message to me, so it gives the message "please ask a parent and use the words please". Cute if it would allow me to do this.

Logging into my account it shows I have Xbox Ultimate; I only want PC on my log in as I do not play all the games he does. I am fine with paying for Ultimate and PC as two subscriptions just do not see that as an option anywhere.

If you give some more information about what happens when you buy the Gold as to how it's getting to your account, we can try to help troubleshoot here.

Outside of cancelling or contacting support, you can just set the console as your Home in order to share the Gold with your son. https://support.xbox.com/en-US/help/hardware-network/console/my-home-xbox

You can contact support by requesting a call back or chat with them at http://support.xbox.com/contact-us If you don't see those options, change your category/topic until you do. Billing & Subscriptions and "I don't recognize a charge" usually works for me.

Cancel means it will cancel your active subscription. It's not giving you the option to cancel next year's subscription since that one hasn't started, unless you mean it's only giving you the option to turn off auto-renewal.
