OK, so after playing with this for a month, I think I'm going to uninstall or disable the extension until Apple decides to make it more user friendly. The utility of it on Chrome is super limited by the fact that it ALWAYS wants me to enter a six digit PIN on every website to enable the extension to pull a saved Keychain password. And, it can't actually generate new passwords on Chrome. And the fact that Safari on my iPhone/iPad can pull a saved Chrome password through Keychain means I'm probably better off having Chrome generate new passwords for use on my iDevices than generating new passwords in Safari/Keychain and then having to enter PIN numbers to use those passwords on my PC.
