Rental movie won't start download
I recently rented a movie and it won't even begin to download. It is in the "TV" app on my iPad and next to it is the blue and white download cloud and arrow. When I push it, it gets transparent like it's going to start downloading but then it just goes back to the original icon. No loading spin or pause button ever comes up. I have more than PLENTY of room on my iPad and I'm frustrated why it won't even tell me what is wrong.
HELP PLEASE!
