PWA swipe down page refresh

One thing I notice with PWA implementation that is immediately apparent and differs from a native app, is the lack of a swipe down refresh for the page.  I can see it being confusing for members on the PWA but it never gets updated automatically or with a swipe, you rather have to navigate specifically to a link or click the site logo at the top to re-navigate and reload the site.  Would be good to add this capability in the future as it will make the PWA behave more native-like.
