I have apps with a lot of audio files, and they load into the Chrome browser fine on the first time. After that they take a long time to load (and sometimes they don't seem to load at all). When I delete the offline.json and sw.js files then they will always load fast without hanging up.
Here is the cp3 file: 1drv.ms/u/s!AobC4q3rBlr6yuBL2sDU1wXwsqd58g
This is an empty project but with a lot of audio files.
Steps are:
1. export to html5
2. load to a server (from things I've read it has to be https)
3. Run it.
4. Close the browser tab and then reopen the app (it may also hang up on a refresh, but not all time).
5. go into F12
result of f12:
sw.js:11 [SW] Update check failed: TypeError: Failed to fetch
