Web Filtering

Hi. I installed Sophos yesterday on a new Pixel 2. After using the default Chrome browser yesterday and again today, I would have expected to see something showing under Web Filtering in the statistics page but it's just empty.

Web filtering is definitely enabled and I went through the steps of allowing Sophos access under Accessibility.

There is also nothing related to Web Filtering in the main Sophos log.

Shouldn't stats start populating by now? How can I be sure pages I visit are being intercepted and checked by Sophos?

Thanks in advance for any assistance.
