Hi my son had a Xbox one with a gold pass and upgraded to a xbox x with 2 years ultimate. When I setup his xbox x with his same account his gametag had ultimate subscription the rest of his gold pass was put on my gametag on the xbox x. But when he signs in some days his gametag changes to gold pass and my gametag has ultimate which stop him downloading gamepass games to his gametag. ...

My game tag was changed for what was said to be inappropriate. I was not told untill after it was changed it was not inappropriate. Now my people don't know that it's me..I think the game tag that was picked for me is inappropriate if the one I had was inappropriate.
Furthermore if I'm able to type in a gametag or pick one pre generated at the making of my account then why is it not posted up front to let ppl know that if we type our own gametag from hthe get go its using up the free gametag change.this is unfair and
downright stupid. If what I picked as a gametag was inappropriate then why was i able to have it for so long.I pay for the gold live I should be able to at the least be able to pick a tag that has my name in it my name is not joey and I'm not scary
