I have been a 1Password user for a while, but never upgraded to a monthly membership until recently & had a standalone vault being synced via Dropbox.
I use 1Password on my mac and my iOS devices. When I move to the 1password.com membership, it copied my standalone/local vault to the web one, but left the other one around & disabled dropbox syncing across the devices. I made a mistake and never deleted the standalone/local vault on my various devices. I have inadvertently saved or changed passwords for certain websites in different standalone/local vaults on different devices. I realized this when I could not log on to a website from 2 of my 3 devices, but the 3rd one had the right password stored in the standalone/local vault & I was able to log in. Now I don't know how to sync the latest password across unless I go through individual device and compare each password by date/time stamp.
Can you please help?
