Problem with auto-fill

Loyal 1Password customer since 2012. Many thanks for the great product in the last decade.

I just upgraded to 1Password 8 from 1Password 7.

I have the following issue with auto-fill in multiple browsers. When I try to auto-fill from the keyboard with Command \, I receive the message "1Password can't verify that [BrowserName] should have access to your [ITEM] item. Do you want to fill it anyway?". The options are "Fill Once," "Fill & Update Login," and "Cancel." The "Fill Once" and "Fill & Update Login" options do not work.

I am on MacOS Version 13.4 (22F66), and I have the same issue with Opera, Safari, Firefox, and Chrome (all with most recent version) !!! I saw the problem in many closed discussions in 2022 (e.g. https://1password.community/discussion/comment/653947#Comment_653947) but still without resolution after a year. I will certainly not try beta versions, as suggested.

What is the status as of July 2023? My workflow is completely disrupted, and 1Password is essentially useless in this current state. I allow myself to share my disappointment, since version 7 worked perfectly fine. Without resolution, I will have to revert back to version 7, or more likely since it is no longer supported, switch to a different product.

1Password Version: 8.10.8
Extension Version: 2.12
OS Version: MacOS Version 13.4 (22F66)
Browser: Opera, Chrome, Safari, Firefox
