1Password X Beta seems to connect to 1Password 7 Beta without issue in both Chrome and Firefox. But there are two issues.
1) 1PasswordX isn't triggering unlock via TouchID, but 1password 7 does when unlocked with the app or menu bar app.
2) The menubar app insists that the browser extensions aren't installed. I'm constantly prompted to install the browser extension for whichever browser I happen to be using at the time. .
In the past, quitting 1password 7 has fixed the issue, but not today. Not even a reboot helped.
