If I try to inspect a player via the Message / Chat window, I do not get a Profile option for players who are on Xbox (my platform), even though I do get the option for players on other platforms.
I noticed that in the Communication > Friends > Recent Players list, this works as expected. So I'm left to assume that not having the option within the Chat window, it must be a bug.
Also, please note that I have no clue if this bug is specific to Xbox, but I figured I'd report it as such since I can't verify it elsewhere at this time.
