Safari extension stops unlocking and filling [See pinned response]

Just wanted to chime in as well -- I've had Safari issues including this, and more. Unlike the original poster, mine have persisted much longer than the most recent update, so they may be overlapping but not the same.

Currently I have virtually zero 1password functionality in Safari (with the extension) because I cannot get it unlocked.

1. If I click on the 1PW icon in fields to select a login and fill it, hovering brings up a black tooltip that says "Unlock 1Password," but clicking the icon simply does nothing.
2. Clicking the 1password icon in my browser toolbar opens the browser extension interface with a "Unlock 1Password" button. Clicking that also does nothing.
3. The only ways I can fill my login info is Cmd+\ and using the desktop app to fill, or (since that sometimes also bugs out and just doesn't fill), Cmd+\ followed by manually copying + pasting the login info into the browser. 
4. Unlocking the Desktop app, either via Cmd+\ or clicking the app icon from text toolbar, dock, or applications folder all work fine

Prior to the unlock issue, for weeks I was able to get 1Password unlocked, but often only via the browser toolbar button, not the icon on login fields. Once the browser extension was unlocked, the icon in login fields would reveal dialogs to either fill or create a new login. There were still a variety of issues:

1. Clicking a login in the login field 1Password dropdown would do nothing -- it simply wouldn't fill (I would have to fall back on a Cmd+/ autofill).
2. Opening the 1Password dropdown would say there was no login for this site, even though there is, and autofilling from the Desktop app with Cmd+\ worked.
3. Generating a new password for a site would work, but I would get a 1Password error that the new password could not be saved or that 1Password could not be unlocked.

All of the other Macs in my family + a friend I set up with a 1Password account all have similar issues. 1 of those is an older (outdated) Intel Mac, but the rest are new M-series ones (with one being brand new); all are up to date.

I've been meaning to create a separate ticket with an array of screenshots so will try to do so soon, but for now, wanted to add a datapoint in case helpful for the development team as they hopefully debug this and push updates!

I will note, its easily possible that restarting my browser or other simple troubleshooting would fix the Unlock issue and temporarily fix some of the others -- but the point of this was to provide troubleshooting intel so the development team could work on not requiring user intervention, so I have not yet restarted. In either case, Safari has had consistent issues for at least all 4 Macs I support in my family, so it does not seem like an isolated fluke to me.

Thanks!
