One other thing to note using the Chrome Lighthouse report, is that it generates a report that includes a PWA report, whether you have a PWA page or not. This feature does provide useful information, about the manifest page if you have a PWA site, but it you don’t have a manifest page, i.e. you don’t have a PWA site, then the PWA “errors” can be completely ignored.
