Hi Ashley, thanks for the reply, I tried clearing my cache, deleting the sw.js and offline.json uploaded it, then upload a new version, it's still not updating to the new version, I thought it would disable the service worker.
I know Service Worker suppose to be the better solution, but some of my clients could be stubborn, and wanted the solution that already working for them for years, I wish there are ways to easily disable to service worker and not generating error in console.
