Hi, I have a question about whether my next App needs to access IAP.We are now developing a new business that provides programming learning for children, because it involves coding, so we provide PC-based products for this, with teachers teaching video and one-on-one guidance on the Internet.In order to enrich our business, we want to provide an app for children's parents to understand their children's learning and course purchases.So about course purchase here, I want to understand that we provide purchase services on the App side. We use third-party payment like Paypal, AliPay, Wechat Pay. Will it affect our App review and launch process?This is very confusing to me and would really like your help, thanks! :]
