I have the same problem as neoz7.
My profile is coming up "This user has chosen to keep their profile data private." but I have absolutely no idea how to change this, I went onto xbox.com to see how my profile looked for anyone browsing but nothing is showing: http://www.xbox.com/en-gb/Search?q=Unity+Bluefin
I went into my account and edited all the privacy date but again after making sure games and achievements etc were open for anyone nothing is displayed. Not sure exactly what I am doing wrong.
