i'm on an iPad Air with iOS 8.4.1, 60 gigs of memory with 37.7 gigs of storage left, so no problem with storage space. i have to download a biology textbook on ibooks for school, but for some reason, it just won't download. i've tried everything, from hard resetting to making sure the wifi was fine to trying to delete it (which it wouldn't let me do) to going back to the textbook website and clicking the link again. i went to tech help at my school and they did everything they could but nothing worked, so they told me to go to the apple store. before i do, any suggestions?
