Auto-Fill not working with Windows desktop app

In the browser extension configuration, you can enable integration with the desktop app, so it will inherit the login and unlock from the desktop app. This way using the browser extension is really seamless. It acts as assistant in the background. Just use your browser favorites and surf to some site with a login, and when the login dialog appears, 1Password will offer the corresponding login to autofill, if the url in the browser matches some url in one of your 1Password items. You don't ever need to search or Quick Access or copy+paste. You need to search only if the urls don't match (then you need to update your item in 1Password) or if you intend to login to some desktop app, not some website in the browser.
