title: "Choose File" button not working as a button in mobile app
body: <p>I have created an online web app that is responsive to different browsers(desktop, tablet, mobile) using Bootstrap framework. After which, I converted the web app to a mobile web app and published on Google Play store and downloaded this android app on my phone. </p>
  
  <p>However, I came to realised that the "Choose File" in the form is not working on app in the phone and can't be clicked. It is working fine when accessed on the url with a desktop browser.</p>
  
  <p>Can someone explain what is the problem and what is a solution to this?</p>
