Hi Joseph, thank you for your response.

I am doing well, thank you for asking, i hope you are good too.

I only have one account so i can be certain that it was purchased only on this account.

I have attached a screenshot of the purchase, i just blurred the order number and the visa number so they are not visible. It shows that i have purchased and own FIFA 23 ultimate edition and that the purchase is complete, which it is because ive been playing it since the early release on the 27th of september, but as of today on the microsoft store on xbox, it says i do not own it and that i would need to purchase it again. And what previously said FIFA 23 Ultimate Edition Xbox Series X/S or Xbox One, now says Standard Edition. And it is saying that i have only purchased the standard editions instead of ultimate editions. i do not understand why it is doing this, but i would like my ultimate edition back as that is what i purchased.

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Scott

Exists the possibility that you purchased the game with a different account.
Let's try to find the account used to purchase this game

For this please go to your Microsoft account order history
https://account.microsoft.com/billing/orders

Once there, make sure to change the "3 months" filter and use instead "All available" next to "Ordered within"
Then start looking each item purchased with your account and see if you're able to find the game with order status "completed"

If you have more than one email please check the order history with each one

(Feel free to share screenshots, but please conceal personal information. No one here can access directly to your account)

That's strange, from your side everything looks good. I think that the best option is open a chat with Microsoft instead of the callback

You can do it using the contact us page, the chat option appears depending on the category selected.

You can try changing categories until you find the option (is not necessary that you choose the category that best suits for you)
