Since upgrading my ipad2 to ios8 I keep getting a niggling message box popping up which says "Unable to download item...done/retry". I have absolutely no idea what "item" it's referring to, and try as I may I simply cannot find any programme or app which is attempting a download of anything. Does anyone have any idea where I can look to see what is trying to download? At first this was a minor annoyance, but is now becoming a complete PITA!!!
