React Native android app not working in release

maybe you need to add android:usesCleartextTraffic="true" inside the application tag in the AndroidManifest.xml .

Something like this:

<application
  ...
  android:usesCleartextTraffic="true"
  ...
>
   ...
</application>

I think the issue is because it's an http request.
