1Password is not able to auto-fill information within drop-down authorization panels under the final build of the new Chromium-based Microsoft Edge. This used to work as intended with the alpha and beta releases of the browser.
I waited a couple of months before reporting the problem but the issue is still present as of Microsoft Edge 84.0.522.63 and 1Password 7.6.780 using 1Password Extension 126.96.36.199.
1Password Version: 7.6.780
Extension Version: 188.8.131.52
OS Version: Windows 10 version 1909
