Hey everyone, to provide some context, the issue with using a keyboard shortcut to unlock/fill via 1Password in Chrome stems from a Chromium bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1364487
We reached out to the developers at Google early on, and they made some updates, which is why things are working in Chrome Canary. Hopefully the fix will come to the stable version of Chrome sooner rather than later.
We do recommend unlocking via the 1Password desktop app and filling via the inline menu until there is a better solution. Another option is to use a different browser (like Safari or Firefox), as they are not affected by this bug. The last option is to set up Chrome Canary, which I've tested myself and 1Password does work well there.
I hope this information clarifies what is going on with this particular issue. Let us know if you have any other questions.
