ng-server reload page but not really update until I manually refresh

Question

The app development using 'ng serve' has been fine.

But recently, even though, the browser refreshes itself after some changes in Angular code while running ng serve. I have to manually refresh page.

I tried ng serve, ng serve --hmr and ng serve --hmr --poll=2000. All has no go.

I also did

echo "fs.inotify.max_user_watches=524288" | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
