Ionic 5 starter Angular not work in Android device

i create a new project with CLI:

ionic start myApp

I select Angular type and blank project.
I add the Android platform using cordova command line and I run the app.
The app started I have a blank (white) screen after splashscreen instead of the home page.
The problem is in index.html:

<base href="/" />

that it should be:

<base href="." />

Where can i report this problem to update the repository?
