Unable to import PDFs – Papers 3 - Reference Manager Review

The only way to import PDFs into Papers3, is to use Dropbox. Since I cannot access Dropbox through Papers3, this app is essentially useless. All of my PDFs are on my iPad, yet there is no access to “Files” on this app. There are so many ways to store PDFs, but they insist on using Dropbox. Dropbox refuses to provide support for 3rd party apps trying to gain access, and Papers is no help, so my advice is to try another reference manager, not this one.
