title: Web app manifest does not meet the installability requirements
body: <p>I try to make a progressive web app, but Lighthouse says, I don't have enough icons, here are the Problems by Lighhouse:</p>
  <pre><code>Web app manifest does not meet the installability requirementsFailures: Manifest does not have a PNG icon of at least 144px.
  </code></pre>
  <pre><code>Is not configured for a custom splash screenFailures: Manifest does not have a PNG icon of at least 512px.
  </code></pre>
  <p>and there are two errors in the Fast and reliable &quot;tab&quot;, but this shouldn't matter I think?</p>
  <p>Here is my Manifest.json:</p>
  <pre><code>{
    &quot;name&quot;: &quot;PWA Test Tutorial&quot;,
    &quot;short_name&quot;: &quot;PWA&quot;,
    &quot;start_url&quot;: &quot;.&quot;,
    &quot;background_color&quot;: &quot;green&quot;,
    &quot;theme_color&quot;: &quot;red&quot;,
    &quot;display&quot;: &quot;standalone&quot;,
    &quot;prefer_related_applications&quot;: &quot;false&quot;,
    &quot;icons&quot;: [
              {
                &quot;src&quot;: &quot;testLOGO.png&quot;,
                &quot;sizes&quot;: &quot;512x512&quot;,
                &quot;type&quot;: &quot;images/png&quot;
              },
              {
                &quot;src&quot;: &quot;192.png&quot;,
                &quot;sizes&quot;: &quot;192x192&quot;,
                &quot;type&quot;: &quot;images/png&quot;
              },
              {
                &quot;src&quot;: &quot;512.png&quot;,
                &quot;sizes&quot;: &quot;512x512&quot;,
                &quot;type&quot;: &quot;images/png&quot;,
                &quot;purpose&quot;: &quot;maskable&quot;
              }
            ]
  
  }
  
  </code></pre>
  <p>Where is my Problem ?
  Do you need some more Information ?
  Thanks for your Attention</p>
