When I go to a website, sometimes autofill is available and sometimes it's not. Then I have to either copy and paste both user name and password or, as I just learned, drag each option to its proper line. This is in Safari and I'm running Mojave, though the issue seemed to start with an upgrade. I'm wondering why autofill isn't present always.
