I turned on Dropbox syncing on my Mac OS X, and I tried to sync it with my iOS 1Password app. I have looked at my dropbox folder, and there is a .agilekeychain file on dropbox.com, my Mac OS X Dropbox app, and on the Dropbox iOS app. However, whenever I try to sync an existing vault, it pops up "Not found. No .agilekeychain ...." I've tried everything. Re-installing, restarting, re-syncing, etc.
1Password Version: 5.4.3
Extension Version: Not Provided
OS Version: iOS 8.3
Sync Type: Dropbox
