Xbox Live Gold - subscription is active (as per inforamtion in my account) but not...

So when you go into settings and go to subscriptions it is still showing as active till November of 2020?

Does it show the same thing when you sign into your account at account.microsoft.com/services?

What happens when you try and start a party or join a multiplayer game? Does it say you need to purchase gold? or give you any sort of error message?

If you got the game through Games with Gold for XBox One then they require an active Gold subscription to play as per the FAQ here: https://support.xbox.com/en-AU/my-account/xbox-live-membership/games-with-gold-faq

Specifically

What happens to my Games with Gold games if I cancel my Xbox Live Gold subscription?

On Xbox One, you’ll no longer be able to access your Games with Gold titles if you cancel your subscription. However, if you decide to renew your subscription at any time, you’ll be able to access and play your previously redeemed Games with Gold
titles again.

Once we were able to get a game with gold successfully it will not be removed from our account but we should have an active Xbox Live Gold subscription to continue playing the game.

If it's asking you to buy the game with an active Xbox Live Gold subscription it means that it is obtained using a different Microsoft account.

Hello Danico,

You need an active Xbox live gold subscription to get the free games with gold. You can go to settings>account>subscriptions and see if you have an active Xbox live gold subscription.

Also make sure you have a internet connection.

Thanks,

Brad
