hii submitted app yesterday to review, This morning I was surprised that the application was rejected, Reason 4.3 Design: Spam.And I've introduced an application programmed by myself, and a unique design.This message I receivedGuideline 4.3 - DesignWe noticed that your app provides the same feature set as other apps submitted to the App Store; it simply varies in content or language, which is considered a form of spam.The next submission of this app may require a longer review time, and this app will not be eligible for an expedited review until this issue is resolved.what should I do ?
