Answer 1

This is happening because of long SplashScreenDelay time.

Replace

 <preference name="SplashScreenDelay" value="22000" />

with

< preference name="SplashScreenDelay" value="2000" />

Answer 2

Try Updating your main.ts file as below

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';

import { AppModule } from './app.module';
import {enableProdMode} from "@angular/core";

enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);

and build your app with --prod flag
