I changed my gamertag over a week ago and my friends tell me that in Xbox Live parties my old gamertag still appears. I though that it would have changed by now; why has it not changed? Will it ever change?
Note: My gamertag has changed in-game, on my profile, in parties (but only on my screen), and on my friends' friends list. The only issue is people in parties with me view my old gamertag.
