They broke it.

The new version of the app does not work. Out of a 10 page document, it will export 4 pages. If I try to upload to dropbox, the document is queued for upload, but never does. The only way to export a document is to export it to messages and send a message to myself. Even then, all the pages are not exported. Do not use for important material
