Autofill drop-down menu not showing

Just installed 1P8 & Safari extension 2.3.3 ... have quit & restarted both with no improvement in this issue. This issue is present with every website I've tried

When I click in a field 1Password can fill (login, credit card payment info, etc.), the autofill drop-down menu that would always appear when using 1P7 never appears with 1P8 + Safari extension. Additionally, clicking on the 1Password icon in the field does absolutely nothing. I have to mouse up to the toolbar icon or use the keyboard shortcut to auto-fill anything.

"Show autofill menu on field focus" is enabled in the Safari extension settings, and I've tried toggling the setting off & on... no improvement.

1Password Version: 8.7.0
Extension Version: 2.3.3
OS Version: 12.3.1
