Hi FreddieLewis1,

Thanks for reaching out to us in the forums for this issue. If you haven't already done so, I recommend removing your profile from the console and then adding it back on to see if this then allows your profile to read your new Gamertag once it is again
downloaded.

Give this a try and let us know the results.

I hope that this helps you out!

Didnt helped unfortunately

Anyone?

Me either it actually made it worse, my old gamertag that I paid for is showing up still and it shows for all of my friends on friends list. And when I look at my account it says my old gamertag then my new gamertag below it but smaller.
