Started for me with B47. Even if I disable Sync, and add Dropbox again - no Sync. Nothing.
No matter if I use my iPhone 5 or my iPad Mini Retina - the result (no sync) is the same :-( :-(
UPDATE: I now did the obvious. I delete the Beta from my iPhone and reinstalled it. Right now it is downloading the initial Dropbox 1Password Database. Hopefully it will work also once I add new items.
Hello @rosenkrieger ! Glad to hear it! I saw this post just after replying to you on other threads. Let me know how it shakes out for you.
