Pinned URL not triggering password manager

When I open a URL that is pinned in my taskbar the password manager does not recognise the site and offer its stored login info.
Reloading the tab or going to the site via password manager works.
‘Bug’ or feature of the password manager??

This has happened a couple of times to me also.
simple solution is to click your orange square key avast password icon extention which is normally shown on top right of screen (win 10) and as long as your vault is unlocked it will show the loging for that site at the top of the vault list.
could be a bug but who knows.
