I was trying to update my iOS app and I received some warnings about three missing icons.
Missing recommended icon file - The bundle does not contain an app icon for iPhone / iPod Touch of exactly '120x120' pixels, in .png format.
Missing recommended icon file - The bundle does not contain an app icon for iPad of exactly '76x76' pixels, in .png format.
Missing recommended icon file - The bundle does not contain an app icon for iPad of exactly '152x152' pixels, in .png format.
I don't know if I have to add these icons too and where to add them or if a have to replace them for the ones that the app already has (57-114 for iPhone and 72-144 for iPad).
