can't disconnect Twitter from Xbox Game Bar

Thanks for your answer. Actually, I meant the link specifically for the game bar (there is a difference between linking to the entire Xbox account and linking only to the Xbox game bar, for some reason).

Any idea?

I found the solution: Deleting the Gamebar credentials in the system control solves the problem.

Just in case anyone has the same problem.

Hello lennovative

To disconnect your Twitter from your Microsoft account you can do it by going into settings on your Xbox One console/settings/Account/linked social accounts/on Windows press Windows key+G then the gear icon/accounts.

Hopefully This Helps 🤘

Twitter login doesn't work in the Xbox app or Xbox Game Bar.

You can try linking on PC via the Xbox Console Companion app, or the Game Bar (Win + G). Just head over to Settings and click Twitter to link your account.

If this doesn't work, you can try deleting the link from Twitter's end by going to
More > Settings and privacy > Apps and sessions. Look for either
Xbox Game Bar or Xbox One Social and revoke access for these apps. By doing this, you're removing any Xbox accounts linked to your Twitter handle, basically starting off from scratch.

Hope this helps.
