Our application was already on the app store before, we did not change the app icon from the first time our application was approved to the app store in 2017.But recently when I submit application to app store, we received this reject message: "Guideline 4.3 - Design We noticed that your app icon is still identical to the icons of other apps already submitted to the App Store. Apps that use the same icon make it difficult for users to find apps and are considered a form of spam." We need help. Thanks
