I use Scrivener on my Mac and recently downloaded the app to use on an iPad. Dropbox accounts are linked and synced and in the Dropbox index I can see the Scrivener project I want to work on. I moved it to the app folder on Dropbox as suggested but there doesn’t seem to be any way to open it. The app just asks me to create a new project, not to open an existing one. What am I doing wrong here?
