Cannot download apps on family sharing for my kid.

My 12-year-old’s child Apple Account is in my Family Sharing group. She cannot download even free apps; the App Store says ‘Payment Not Completed.’ Her Apple Account says a payment method must be verified. I am the family organizer, Purchase Sharing is enabled, I’ve verified my existing card and added a second valid card, and there are no paid purchases showing in her recent purchase history. Please check whether her Media & Purchases account has a billing/verification hold and reset or clear it if necessary. This is for apple support I don’t know where else to add this and before I post this I wend back and forth with OpenAI GPT with no success in troubleshooting this. I mean what to do the kid needs to download apps , it makes this unusable. Please help.
