Can't redeem an xbox games with gold game

It has always been like that not unless there will be an update regarding in redeeming Xbox 360 games with gold on the website. Xbox 360 marketplace has a different structure than on Xbox One Store. Xbox 360 games with gold on the website will need a payment
method. In Xbox 360 console, you won't need one. Currently, you can't redeem Xbox 360 games with gold using Xbox One console and still under progress about redeeming Xbox 360 games with gold on Xbox One console. Either get the games using an Xbox 360 console,
or get the games on the website with a payment method.

Dear StéphaneDelarue,

Please read this from Xbox FAQ

What if I can't access Games with Gold even though I have a paid subscription?

When you try to access Games with Gold, make sure you're using the gamertag that has the Xbox Live Gold or Xbox Game Pass Ultimate subscription. If you redeemed a promotional Xbox Live Gold token as part of
your subscription, you won't be eligible for Games with Gold. If you used a prepaid code to sign up for Xbox Live Gold, make sure it was successfully redeemed.

If you live in one of the countries or regions listed above under "Offer and eligibility" and still can't access Games with Gold, contact Xbox Support.

Happy gaming

Did you try it on your browser, an Xbox 360, Xbox One or on the Xbox app? Do you have valid payment details for the Xbox 360?

Okay, quick update! I tried redeeming the code with a different account which doesn't have Live Gold and it works. I didn't click Redeem but it does work. This leads me to believe that I can't redeem a game I already have through Games With Gold.

I'm having this problem with my Xbox one. My problem is I have gold (can't redeem any codes because it claims I already have gold) and can't play Netflix or any games online because it claims I don't have gold
