Did you look in the app drawer? You said it's not on your home screen but you don't say if it's in the app drawer.

Sorry. Sir their was typographical error in my original post. In MI phones there is no app drawer. On installation of any app it directly creates icon on home screen.
Anyways thanks. My problem is been solved. I have uninstalled the app from Google play store and had immediately installed the same.

Thanks.
