The app provides loan services but the domains listed on the app's Product Pages are not clearly under your control or ownership. Since users may use these domains to contact you to request support, the domains used on the Product Page for loan apps must be under your control or ownership.
Next Steps
Update the Product Page metadata in App Store Connect to only include domains that are associated with Apple Accounts registered to your developer account.
Please note that apps used for financial trading, investing, or money management should be submitted by the financial institution performing such services, as required by App Review Guideline 3.2.1(viii).
We have already provided the domain name and financial-related supporting documentation, but the application was still rejected. We are unclear about the root cause and kindly request technical support from Apple's review team. Thank you very much for your assistance.
