Live change updating not working after PWA

I built a PWA for one of my projects using npm run ionic:build --prod

Now, when I launch any of my other projects using ionic serve or ionic serve --lab, editing a source file does cause an immediate rebuild, but the changes are not reflected.

Relaunching the app also doesn’t show the changes.

What could be the reason for this and how do I fix it ?

My ionic info :

cli packages: (C:\Users\Sidharthramanan\AppData\Roaming\npm\node_modules)

@ionic/cli-utils  : 1.10.2
ionic (Ionic CLI) : 3.10.3

local packages:

@ionic/app-scripts : 1.3.12
Ionic Framework    : ionic-angular 3.5.0


Node : v7.7.3
npm  : 4.1.2
OS   : Windows 10

Anyone had this issue before? With their first time creating a PWA?

Fixed the issue : I guess after building a PWA my service worker was still running in the background. So I went to Chrome developer tools --> Application --> Service Worker and unregistered the service worker. That fixed my issue.

Maybe it was running a cached version of the app. Not sure.
