title: Ionic 4 Need to update by app on playstore
body: <p>I am going to publish my ionic app on the play store. But I need to add an auto-update in my app. like when the new version is an available user will update automatically. I learn about ionic deploy but some people say ionic deploy only change the content of the app, not the native code( native code mean to add a new function, page, etc) </p>
  
  <p>If it is true so what is the way to update my app auto? I know the plugin of app update but it will not work on ios. </p>
