The text view is behaving oddly when using VoiceOver. Tapping it to focus it, it only reads the line of text that you tapped, rather than the entire text view content. Comparing that to Messages, when you tap in the the text view, it reads the entire contents. Note that when you don't tap in the text view but rather swipe between elements, it properly highlights the entire text view and reads it all.
