Cordova App icon is showing default cordova app


i am building app using cordova and ionic . i have added icon.png and splash image under resources folder and i had run ionic resources to generate icons and splash images. i have also included icon-1024.png(1024px, 1024px) in config.xm file for play store icon.
Now when i upload the app to app store connect, the app icon is showing default cordova icon.
can anyone suggest what is gone wrong?.. thanks in advance.
