Based on the comments, an update will not take place if you did not increment the version number of the application.
If you change a native resource such as the app icon, but do not increment the application version number then the check for a new version will not see the update because it is basing it on the version number.
Update the version number and upload the updated .apk and .ipa; the update should then happen.
