title: Oreo Notification Icon not displaying
body: <p>I have Used targetSdkVersion 26 &amp; Notification Icon is not displaying . When I changed to targetSdkVersion 20 it's working correctly. But when I am uploading the app to play store it's not downgrading. How can I show icon in targetSdkVersion 26. <a href="https://i.stack.imgur.com/aYhjG.png" rel="nofollow noreferrer">Notification small icon 72X72</a>,
