Screen Time passcode not updating on son's iPhone after reset

Hello Apple Support,

I am experiencing an issue with Screen Time parental controls on my son’s iPhone.

I am the Family Sharing organizer and manage my son’s Screen Time settings from my own iPhone.

The problem is as follows:

1. 
   
2. I forgot the original 4-digit Screen Time passcode.
3. 
   
4. 
   
5. I disabled my son’s parental controls on my iPhone and set them up again.
6. 
   
7. 
   
8. I successfully created a new 4-digit Screen Time passcode.
9. 
   
10. 
    
11. However, my son’s iPhone still has the old restrictions, including scheduled access from 7:00 AM to 9:00 PM and app usage limits.
12. 
    
13. 
    
14. When I try to change or disable these restrictions on his iPhone, it still asks for the old Screen Time passcode.
15. 
    
16. 
    
17. The new passcode does not work on his device.
18. 
    
19. 
    
20. I cannot find an option to reset the old passcode.
21. 
    

Could you please help me reset or remove the old Screen Time passcode without erasing my son’s iPhone or losing any data?

I would also like to restore proper synchronization of parental controls between our devices.

I can provide screenshots if needed.

Thank you for your assistance.

Kind regards,
