Won't sync anymore – Tiny Password - Secure Password Manager Review

Used o sync fine thru dropbox, but now my iPhone 5s and iPad Air2 will no longer sync with each other. What's the problem? Any fix? And, when I click "Report a Problem" in iTunes, I'm taken to the company website, but there's no icon for Tiny Password. Is this app no longer supported?
