I seem to have a strange issue with file sharing - the list of documents in Goodreader, Cine X, or Pages, for example disappears if I click on a different "app" on the left side (MaxJournal, for example, which has no documents) and then return to either of the main apps above. The documents appear to be all there in those apps when "file sharing" is first opened and I can perform any of the usual tasks, but then simply "disappear" if I click on another app. I'm unable to load another document into file sharing or even use it until I restart the connection. Has anyone experienced a similar problem, or perhaps has a solution? That's a little garbled but hope it makes sense!
