I'm confused about TV shows on my ipad. I downloaded 7 episodes from a series. I have watched all of them except the last - the first 4 on my ipad, then the next 2 on my laptop. I cannot download the last episode on my ipad, although I have, or I think I have, deleted all the other episodes. However, I see three downloads on my ipad that I cannot access. Episode 7 says "download error. tap to retry." When I tap that, it says Episode 7 could not be downloaded at this time. When I go to the Video app on my ipad, there is nothing there. I thought I could totally delete all episodes, then just re-download Episode 7, in case space was an issue. I keep going in circles, and it's driving me crazy. Please give me the piece of the puzzle that I'm missing!!!
