I've read through old posts (latest being from 2015) describing the same issues I'm having. I changed my master password on my iphone and it's not syncing with my other devices. I have the latest version of 1password and syncing through dropbox. Any suggestions other than changing all devices manually?
1Password Version: 6.3.1
Extension Version: Not Provided
OS Version: ios 9.3
Sync Type: dropbox
