  <p>How could I solve it?</p>
  
  <p><strong>Finding the problem source</strong></p>
  
  <p>The problem of app not usable because I changed the packing name from </p>
  
  <pre><code>io.ionic.starter
  </code></pre>
  
  <p>to Windows app store information that provided by Microsoft developer account.</p>
  
  <p>when I test the app locally becomes white screen because the package name and package family name are changed.</p>
  
  <p>How do I fix this and connect between them to upload my app?</p>
