React-hot-loader doesn't propagate changes - reactjs

Question

My problem is that react-hot-reload detect the changes and the modules that need to be update, and apparently does update the modules, but nothing in my browser changes.
Here's the version of the libraries I'm using:
react - 16.8.3
react-dom (patched by react-hot-loader ) - 16.8.3
react-hot-loader - 4.8.0
webpack - 4.29.6
Below, my webpack-dev-server config:
historyApiFallback: true,
hot: true,
stats: 'none',
quiet: true,
port: port,
host: host,
Relevant part of my webpack config
entry: [
'react-hot-loader/patch',
'webpack-dev-server/client?http://localhost:8080',
'webpack/hot/only-dev-server',
'./src/index.js',
],
resolve : {
alias: {
'react-dom': '#hot-loader/react-dom'
}
},
My .babelrc:
"plugins": [
"#babel/plugin-transform-flow-strip-types",
"#babel/plugin-proposal-class-properties",
"react-hot-loader/babel"
]
My initial component:
import React, { Component } from 'react'
import { hot } from 'react-hot-loader/root'
class App extends Component<PropTypes, StateTypes> {
render (): React$Element<*> {
return (
<Router>
<Switch>
<Route
path="/home"
render={ (props: Object): React$Element<*> => <HomeView {...props } /> }
/>
<Route component={ IntroView } />
</Switch>
</Router>
)
}
}
export default hot(App)
Lastly, my entry file:
import React from 'react'
import ReactDOM from 'react-dom'
import App from './app'
const appContainer = document.getElementById('appContainer')
if (module.hot) {
module.hot.accept()
if (appContainer) ReactDOM.render(<App />, appContainer)
} else if (appContainer) {
ReactDOM.render(<App />, appContainer)
}
If I do any code change that was supposed to trigger an update, that's my console:
[WDS] App updated. Recompiling...
[WDS] App hot update...
[HMR] Checking for updates on the server...
XHR finished loading: GET "http://localhost:8080/df32ff4...hot-update.json.
[HMR] Updated modules:
[HMR] - ./src/library/protons/ModalWorkflow/sandbox/workflowStepOne.js
[HMR] - ./src/library/protons/ModalWorkflow/sandbox/index.js
[HMR] - ./src/configs/routes.js
[HRM] - ./src/views/intro/index.js
[HRM] - ./src/view/home/index.js
[HRM] - ./src/app.js
[HRM] App is up to date.
Browser doesn't reflect the code changes at all.
No errors, no warnings.
Tried several different approaches to check any potential mistake, but as of right now I'm in this hopeless spot, no idea what else I could try.
