title: After updating new version on play store , it still shows installed app
body: <p>I deployed new version of my android application on google-play-store. As i assume after publishing , it should notify me to update my application. But i didn't receive any kind of notification even after 2 days. When i un-installed my application and reinstall i got latest version of my application. </p>
