cant see my reach service record after name change

so i am getting ready for the mcc on pc so i need to change my name on xbox account and now i cant see my service record for reach is they a fix for that or do i just have to wait ?

For legacy games you need to hop back on and play a little on Xbox Live for everything to sync up. That can be campaign, forge, multiplayer, etc, as long as you’re online.

okay thanks and thought so ^^
