Dictionaries on iOS 9 not working I just updated to iOS 9, and I noticed that the built-in dictionaries, I previously used, aren't working. I had used American English, British English, and Apple Dictionary. Now, when I try to define any word, I get a "No definition found" error. The dictionaries I previously used show a blue circle (while all the others show the cloud download icon).
Sounds like a bug to me. Not even iOS is completely immune to them, even after a long public beta period. So, not a lot that you can do other than wait for iOS 9.0.1 and hope that it will fix that issue with the dictionary.
