When I view players on the Game Manager on PlayFab (Players -> Players screen) there are some not showing up, and no paging options to show some more. But when I recently called the GetAllPlayersInSegment command from server to get a list of players in the "all" segment, I noticed that several missing accounts from that Player screen didn't have a "Display name" although they did have PlayFab Ids. Perhaps the reason why they're not visible is because they are missing their Display Names and the sorting functionality just ignores them? Thought I would ask.
