After creating a PWA with react every thing works perfectly except when i want to open the app with a mobile device android/ios....it displays a white screen with no informations. ///// The app is deployed with IIS manager
my service **service-worker.ts ** `

/* eslint-disable no-restricted-globals */
// This service worker can be customized!
// See https://developers.google.com/web/tools/workbox/modules
// for the list of available Workbox modules, or add any other
// code you'd like.
// You can also remove this file if you'd prefer not to use a
// service worker, and the Workbox build step will be skipped.
