Why is javascript not working and images are not loading in WebView?

Question

Android

Good afternoon. I have a strange situation. I made a WebView application, but javascript does not work and some pictures are not loaded. And when you click on some page, after a reboot, everything loads and starts working.

package ru.djamali.vseza100;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        WebView myWebView = (WebView) findViewById(R.id.webview);
        myWebView.setWebViewClient(new WebViewClient());
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        myWebView.getSettings().setDomStorageEnabled(true);
        myWebView.getSettings().setAppCacheEnabled(true);
        myWebView.getSettings().setLoadsImagesAutomatically(true);
        myWebView.loadUrl("http://www.mysite.ru");


    }
