Stuck setting up new iPad for child.

I went through the steps of setting up a new iPad Pro for my child, including creating them a new Apple ID. I have reached the part when I am trying to set up parental controls, and it is asking me to create a Screen Time Passcode. I enter the new code, then it asks me to re-enter the code. I re-enter the code, and it just sits there indefinitely. There is no error messages. It’s not hung, as I can press the back button, but it will not progress past this point. Just has all four digits filled in and is stuck.
