No Safari Extension for 1Password 8
I just upgraded to 1Password8 on my Mac (12.3.1). The app seems to work ok, but I can't get the extension to load in Safari. The "1Password for Safari" installer seems to think it's installed, but clicking the "Open Safari Preferences" button does nothing. In the App Store, it seems to think the extension is installed also, since it gives me an "Open" button instead of "Install". But clicking "Open" just opens the "1Password for Safari" app which doesn't seem to do anything.
If I go into Safari and manually open Preferences > Extensions, I don't see the 1Password extension listed there. There's no icon in the tab bar like there used to be for 1Password 7. I don't get any autofill suggestions.
How am I supposed to install the Safari extension?
