I turned on voiceover to have iPad read a book to me. Then I couldn't get voiceover off. So I totally shut down the iPad. Now when I try to turn it back on, and go to enter my 4-digit security code, voiceover reads the code to me, then tells me to swipe; but because a swipe means something different with voiceover on, it doesn't swipe the arrow to the right so the iPad won't go any further. How can I remedy this?
