I've been using 1Password Version 3.8.22 on OS X 10.9.4 and syncing with my iPhone 5 running iOS 7.1.2 for ~a couple of years. Recently my Yahoo iOS app locked me out of my account and I had to reset my password. I did this on my Mac and the new password will not sync over to my iPhone version of 1password. I've prompted syncing with the 1password app and also tried switching to iCloud syncing and back to Dropbox. When I try an set up dropbox syncing it doesn't seem to want to complete the process. I get left at a screen saying "Choose a Vault" with a file path to the passwords file "/1Password.agilekeychain" on the next line but it is greyed out. When I select it I get a message saying "The Vault already exists on your iPhone".
Can't make head or tail of this. Please help AgileBits
