1P not populating login fields
I've been noticing this for a while, but it's become really annoying now.
On a website login page, the username field will show the 1P icon. Nothing is being populated automatically. If I Hover over the field, or click the 1P icon in the field nothing happens. I basically have to go to 1P in the browser bar or open Quick Access and copy and paste bother username and password individually. What's going on?
PS Version info as below - yes I know I'm not running the latest macOS but my iMac won't update beyond Catalina, it's too old.
1Password Version: 8.10.4
Extension Version: 2.10./0
OS Version: macOS 10.15.7
