Xbox Series X Child Account Is Always Requiring Password

I have set up a child account on Xbox and signed into the account on my Xbox. I have also signed into my account (family organiser).

However, whenever I sign into the child profile on the Xbox, I always have to enter the account password.

I have checked all the settings I can think of:

Parent account > Privacy & online safety on account.xbox.com

The parent settings in account.microsoft.com/family

The child settings in account.microsoft.com/family

Xbox settings

general > Online safety & Family

Account > Privacy & online safety

And cant see any settings that stop him from signing in without the password.

PS

Straight after entering the password, a green box appears briefly saying something along the lines of "Screen time limits removed". But there are no screen time limits set.
