Hello, I have built a mobile application specifically designed for managing employees within an open-source ERP system. I have enabled an in-app purchase option so users can upgrade their version and access additional features. We are now receiving interest from many clients who want to white-label this app and customize it with features tailored to their business needs. Since we cannot incorporate all features into a standard app due to the unique requirements of each business, what is the best way to upload a white-labeled app to the App Store and customize it according to client specifications? I attempted to upload a white-labeled app but it was rejected with the error "4.3.0 design spam." I am unsure how to address this issue. Thank you.
