Can't create another profile

Hello Tim,

We understand that you're experiencing an issue concerning the inability to create a new profile on your Xbox One console.

We recommend trying a power cycle
of the console.

If the problem persists, try doing a soft factory reset of the
console, reset and keep games and apps to help reset the operating system. Please note before doing this troubleshooting step, make sure to know your email and passwords for your Xbox profiles.

Try this out first and let us know the results.

Try create new profile on PC or Mobile.

I’m sorry to hear you’re having some trouble when trying to create an Xbox profile. Let’s try to sort this out.

For this purpose, I would like to ask:
May I know if you tried using a different device, like your phone, to create your Xbox profile?
Additionally, what about using a different Wi-Fi network, or using your mobile data?

I'm afraid not.Gamertags can't be merged.

Saves are tied to the gamertag that created them & achievements are also tied to the gamertag that unlocked them & can't be moved to another profile.

I think i just figured out the problem. Looks like the latest update messed with family settings. I had to reassociate my son as family in my microsoft account settings. Had to do the same for the other accounts on this xbox. No more login issues. Hope
that helps
