1Password Families for Mac will no longer Auto-fill in Safari

Hi Steph,
Yes, the 1Password icon does display in my toolbar. When I sign in, I am able to see all my entries. Yesterday, clicking on 'Open & Fill' did not seem to work for anything, however today, there was a message in 1Password, saying that they are now hiding competing sign-in methods. 'Open and Fill' now seems to work from the icon in the tool bar, and also from the icon that appears on the sign-in portion of web pages. However, I still have one site that is not working... Certified Federal Credit Union at https://www.certifiedfed.com/#account-login. If I click on the 1Password icon that appears in the 'username' window, nothing happens (it always used to auto-fill). If I click the 1Password icon on the toolbar, the dropdown menu appears, I can select Certified Federal Credit Union / 'Open & Fill' / But then nothing happens with that either.

Three strange things I noticed...
1) Despite the message I received today in 1Password, saying that they are now hiding competing sign-in methods, when I go to the Certified Federal Credit Union sign-in page, I can see the Apple 'Keychain' icon (which can also be used for auto-fill) sticking out from behind the 1Password icon. So it is not "hidden" in that case; it is just behind the 1Password icon, like it always has been.
2) The second strange thing is that my wife has the exact same Mac computer, with the same macOS, and also 1Password Families for Mac, and she also has the Apple Keychain icon behind the 1Password icon on the Certified Federal Credit Union sign-in page, but when she clicks on the 1Password icon (toolbar or webpage), it auto-fills and signs-in with no problem. So this appears to be something specific to my computer.
3) In the notification I received today in the 1Password app, I clicked on 'What's new', and it displayed a list of updates, titled, 'May 30, 2023 - 1Password for Mac 8.10.7'. One of the updates said, "Fixed an issue that could cause nothing to happen when clicking an in-page password suggestion." This is exactly the problem I am having! What is strange, is that my wife has never had that problem logging in to the Certified Credit Union website, while I still do, DESPITE both of us having the latest 1Password update. But what's even stranger, is the fact that when I checked the 1Password app's 'What's new' update list again a few minutes ago, the update description, "Fixed an issue that could cause nothing to happen when clicking an in-page password suggestion" has been removed! It's almost as if someone just realized the problem was not fixed after all, and then removed that update from the list. Isn't that odd?

Anyway, that still doesn't explain why I am not able to auto-fill my Certified Federal Credit Union sing-in info from the 1Password toolbar icon, nor the 1Password in-page icon, while my wife has no problem doing those things on her computer.

Thanks,
