I do not think this is an issue specific to Web.app. I see the service worker install / activation being successful. However, the service worker does not handle the main resource load for some reason. 1568490 3 youennf 2019-09-06 05:54:23 -0700 Tested on a recent build and trivago.com redirects me to trivago.fr which is working offline in mobile Safari.

Also the manifest support this: curl 'https://www.trivago.fr/manifest.webmanifest' -H 'user-agent: Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1' | grep display
