White stub in notification pushed from Clevertap dashboard (Android)

[snghnishant]

Notification pushed from Clevertap dashboard (Android) shows a white stub instead of the app icon in the notification system tray. However, firebase notifications pushed from our custom backend server works fine and displays with the app icon properly.

@snghnishant Please follow the steps here for setting the small notification icon

@darshanclevertap Seems like the issue is device-specific as most of the devices for our app are getting the notification icon. You may close the issue. Thanks for the help.
