When setting up a child’s account. How come when it gets to the credit card part or payment option to add the child account everything stops and doesn’t go any further? It freezes once I get to parental consent and try to add a card

Hello BearMonclear,

Have you been able to try restarting the iPad since noticing this issue? If not, this may be able to help with resolving odd issues that can come up: Restart your iPad - Apple Support

Be sure to also check for any iPadOS updates on the device being used, as this ensures the latest fixes/improvements are applied: Update your iPhone, iPad, or iPod touch

If you're able to connect the device to a different Wi-Fi network, then this can help to rule out any possible conflicts between the existing one and the device.

Cheers.
