New UI changes appear for guest accounts instead of my Main account

hello thank you very much for answering, I have xbox gold, I explain. for problems I could only enter my Fortnite account in a guest account not in the main one and it works well what happens that does not let me do voice chat does not appear as if a microphone
was connected in my main account instead if it leaves me do voice chat normally.

? my question is will it be that you can not do voice chat as a guest account or just have to configure it and if that were the case as I do it? Thank you

Because they were my childrens profiles so they were not online. The XB1 only supports online profiles and guest accounts to your main profile. My daughter likes to dress up her avatar and certain games allow for her to appear in games so the guest account
wouldn't be suited for that.....In other words new profile new email new password for every profile. Simply ridiculous.

No, what im asking is that why do i have the old ui instead of the new ui after i fully resetted my computer and why the new ui only appears on the xbox, xbox console companion and minecraft (from the in-game sign in button)

Were you playing on a guest account and not your main account?

You can not transfer data across accounts.

However, if you haven't much on your new Microsoft account i.e. no purchases, achievements etc, then you can log in with your main email address to your console and use it instead.

If you want to retain data, you will have to change email address associated with your new account to be the email address of your main account. Follow these steps: https://support.xbox.com/en-AU/my-a...nt/change-email-sign-in-for-microsoft-account
