Have exactly same problem everything works, except --prod

Yes but my need production build and release.

run with android v 7.1.4

I change ionic version. v3 to v4. I’am happy.

Did you solve the issue stated in the question in the given environment? It’s absolutely obvious that there are people that built big apps, and the cost to adapt all the developed stack from v3 to v4 is absolutely impracticable, so we are looking for a way to fix the issue in the v3 version.

Basically, what i did was updating ionic

npm i -g ionic

Updating app scripts

npm install @ionic/app-scripts@latest --save-dev

And changing the version of typescript to ^2.8.3

For known reasons, exit the terminal and open a new one, just in case.

This was my solution, also running it with

ionic cordova run android --prod

and debugging with the Chrome Dev Tools helped me to find answers.

Result of ionic info:
