This applies to the newer caching that uses in5.serviceworker.js (instead of the older Application Cache method).


If you've exported a web app with offline cache enabled and after it downloads all of the content, it either only shows the cached content for 24 hours or doesn't work at all offline, try checking the following:


  1. Make sure that your website is on a secured protocol as service workers are only supported on https.
  2. Check if any redirects aren't permitting the service worker to run.
