I have purchased 1Password for my Mac, my PC, and for my iPad. I connected all of them via Dropbox in order to have the data synced. However, quite recently, the Dropbox interface used by the iPad is no longer compatible and I can no longer sync that device. Support suggested that I upgrade to 1Password version 4 for Mac, but I don't know what this will do to my syncing to the PC. Can the latest version of 1Password for the PC read the data file created/updated by 1Password 4 from the Mac?
Help to keep disparate system in sync would be greatly appreciated.
