During the recent Olympiad there was a setting somewhere to choose between the High Definition video stream (also known as "freezes-doesnt work") and the Standard stream (aka "works fine"). Now Im trying to watch the Sinquefield Cup and as far as I can tell the latest version of the app has removed this setting, leaving the HD default as the only choice. So on my devices at least (both my iPhone 5 and a recent vintage iPad), it wont work. Video plays for about 10 seconds, then freezes (audio continues streaming).
