⌘+\ doesn't work on most websites with 1Password 8 for Mac & Safari

Hey y'all, thanks so much for sharing this with us! Based on what you're describing, I think you're bumping into two different scenarios - in the instances where the desktop app is unlocked but 1Password in Safari is not unlocked, this sounds like a temporary disruption to browser integration itself - where the 1Password extension hasn't connected to the desktop app.

With regards to hitting the ⌘ + \ shortcut and nothing happening, is it possible this is occurring on websites where you have more than one matching item? If there are two or more items suggested for AutoFill on a particular website (say you have two gmail accounts, and are trying to sign in at Gmail.com), 1Password won't fill either entry in and instead leaves the decision of which item to fill up to the user. Is it possible that's the behavior you're running into?
