Microsoft Store account is different than Xbox Account supposedly

Hi, Walker. I hope you're doing well and safe out there. I'm an Independent Advisor and I’m happy to help you today.

Sorry about that. Is this the only game that is having this issue? Kindly open the Microsoft Store, then click on the profile picture in the top right corner. A pop-up box will appear allowing you to sign out then once signed out, kindly sign in again using the account that has the game and then open File Explorer using the Windows key + E shortcut.

In the address bar paste the following line:

%userprofile%\AppData\Local\Packages\Microsoft.XboxIdentityProvider_8wekyb3d8bbwe\AC\TokenBroker

If there are Accounts and Cache folders available make sure that you delete them. After removing the cache, try to check the game on the Xbox app again.

That did it. Thank you so much.

I am still having this issue as of July 2021: rapidly flashing login modal appearing and disappearing, the error message "Your Microsoft Store account is different from your Xbox account" appearing on every load of the Xbox app.

Launching the Xbox Console Companion (XCC) and minimizing it fixes the issue with the Xbox app. Meanwhile, the XCC app is aggressively messaging that it is EOL and we should be using the Xbox app. And yet, they seem inextricably linked. So which is it, Microsoft?

I am experiencing the exact same issue. Did you have any success resolving this issue?

Yes, any time I click on something while in the app, a pop-up will happen and quickly close a number of times in a row. It seems like the popup happens whenever it is loading something in the app? Not sure.
