I occurred the WARNING ITMS-90704 when I had finished to upload the App to App Store, just as the following picture shows.
WARNING ITMS-90704:”Missing App Store Icon. iOS Apps must include a 1024x1024px App Store Icon in PNG format. Without providing the Icon in the Asset Catalog or via App Store Connect, apps cannot be submitted for App Review or Beta App Review. Refer to https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/app-icon/ for more information.”
Apparently, I missed the 1024×1024 App Store Icon in the Asset Catalog, but got the chance to add it via App Store Connect, and it’s why the validation was successful which I didn’t realized before. And I tried again after adding the icon, and got the second error: Redundant Binary Upload.
