I'm running the 1P X beta extension from the Chrome Web Store in Chromium Edge beta [22.214.171.124] on macOS.
Since a browser update this week the login pop up box doesn't work, it opens up but the text field remains frozen, the cursor doesn't blink and no keystrokes are registered. Logging in through 1password.[eu in my case]/signin does work; and after that the extension works good.
I was running the stable 1.16.1 extension when the issue first appeared, and then moved to the beta just in case it worked.
