1Password not syncing

Well here I am with the exact same issue. No connectivity issues at all. I changed a password for a login on the desktop, closed out 1Password and 15 minutes later went to the laptop and couldn't get into the recently changed login website. Checked 1Password on the laptop and iPhone and the old password was still there. This is not confidence-building. If syncing automatically takes place once you boot up 1Password, then why hasn't the new password changed on the other devices? Should be pretty instant and automatic, but it isn't.
