I have 1Password on an iPhone and iPad, as well as other computers at work. I had a problem on my iPad, went to sync it with my Mac at home, and noticed the sync field in preferences is totally missing. It is there on the iOS devices. Haven't been back to work to check those machines yet. In the meantime, I have lost all passwords on my iOS devices.
1Password Version: 6.3
Extension Version: Not Provided
OS Version: 10.11.6
Sync Type: Dropbox
