My son have installed Minecraft in my android device.

While playing is he is getting a message that 

"you cannot play on realms because of how your microsoft account is setup. This can be changed in our privacy and online safety settings on aka.ms/accountsettings"

I have seen some links which talks about parental intervention and set the privilege from parent's account. I did that. But still the issue persists. How do I fix it.

Thanks
