Angular Service Workers not work on iOS standalone mode

I am working on PWA with Ionic v4 and Angular PWA service workers. On app.component.ts have a injected service to check if updates are available on PWA and then download and reload.

When I open PWA with the browser the service works fine and If I deploy an update the service worker update the cached PWA and ‘auto-reload’ the page.

The problem comes with PWA/standalone mode, on iOS when the PWA is added to homescreen it not refreshes anymore even killing it with the task app list. Only If I shutdown the device and on again it refreshes the state of the app. On Android devices all works as expected on PWA mode.

This is my version checker service implemented with Angular service worker:

import {Injectable} from '@angular/core';
import {SwUpdate} from '@angular/service-worker';

@Injectable()
export class LogUpdateService {

    constructor(updates: SwUpdate) {
        console.warn('check')
        updates.available.subscribe(event => {
            console.log('current version is', event.current);
            console.log('available version is', event.available);
            updates.activateUpdate().then(() => {
                console.warn('downloaded')
                document.location.reload();
            });
        });
        updates.activated.subscribe(event => {
            console.log('old version was', event.previous);
            console.log('new version is', event.current);
        });
    }
}

This is my package.json:

    "@angular/common": "^7.2.9",
