Today, on my iPad mini, when I select a word by highlighting it and press "define" I am greeted with this message where the definition of a word is supposed to be: "no definition found". I have already pressed the "manage" button and selected the "Apple Dictionary" to download. However after it says it has downloaded, I get the same problem. Curiously, when I select another dictionary -- say, the English New Oxford American Dictionary, it fixes the problem and I can see a word's definition. I have two questions: Is anyone else experiencing this "no definition found" with only the "Apple Dictionary" selected? When going to the manage menu and selecting a dictionary to download, is that taking up space on my device (iPad)? Usually the define feature has worked for me without ever having to select a dictionary to download, so this is strange.
