title: PWA Add home screen is taking time
body: <p>I am trying out to plugin PWA into our mobile website, I have been able to implement all features of PWA without any problem. But I am facing issue while I am trying "Add to Home Screen" feature, it is taking more than 30 secs to create an App Icon on mobile home. This is a bad UX, please advise if we have encountered this issue and what can be done to make it work faster.</p>
  
  <p>Thanks.</p>
