I know this was possible for years - and I happily had a "wormhole" between my PC and my Evernote Notebook - both named PC tp Evernote for convenience. When I dowloaded a new report to my PC (to this folder) it was automatically added to the notebook. It was a joy - but it has stopped. Where do I go to set this up again and how can I be sure it doesn't break down again?
