new gametag not showing

Hello Alexandra I, My name is David. I am an independent advisor, happy to help you today.

I'm sorry that you are having problems with your Xbox Gamertag, remember that;
On Xbox 360 gamertags can be up to 15 characters, including spaces. They cannot start with a number.

On Xbox One, Xbox Series X|S, and Windows: Gamertags can be up to 12 characters, including spaces. They cannot start with a number.

Xbox gamertag changing rules may mean that certain special characters or formats do not update correctly in all areas of the system. In some cases, the old gamertag may appear temporarily until the information is fully updated across all Xbox Live servers and systems.

My suggestion would be to wait a little longer, to see if the problem is resolved, for example, 24 hours

We can also try to log out and log in again to your account in the console and check if the name was updated, but normally this is more of a system problem.

However, below I will leave you a link in which you will have access to the official article in which Microsoft explains how to update the Gamertag

Best regards.

Hello,Terminus808 sorry to break the news but she might have changed her gamertag. Changing your gametag gets rid of the previous gamertag. So if you search for her previous gamertag only her new one will show up not the old one.
