I use 1Password with 3 devices - iPhone 6+ with latest iOS, iPad 3 using iOS 7.12 and MacBook Pro using OS 10.9.5. I sync through DropBox. So, if I enter new passwords on my iPhone the new entry syncs properly. However, if I have a new entry using either the MacBook or the iPad, those 2 devices sync properly, but the new entries won't show up on the iPhone. I go and sync the iPhone and still nothing. I have had to manually enter new information to the iPhone in order to have the same information on the new devices. Interestingly, when I enter the information on the Iphone if it is the exact same information as the information on the other devices, it does not generate a separate entry in those.
