Anyone else notice that achievements and friends created using the Xbox One do not show up on their WP? If so have you found a work around, or what the issue is?
It's because Xbox One acheivements are separate to Xbox 360. If you log into Xbox.com, you'll only see information regarding your prior Xbox 360 life, you're prompted to install Xbox One Smartglass to see anything relating to Xbox One.
Yes, I was confused as well. Hopefully a portal will open up on Xbox.com for Xbox One content at some point in the future..
Use the Xbox One SmartGlass app to view them. The app is still actually functional when not connected to your Xbox One. Hope they integrate it more into WP8 though.
