Content & privacy restrictions is gray out on parent phone

I have all this set up, but when I go to the Content & Privacy Restrictions section and click the button at the top, it goes green for a few seconds and then all buttons and text turn grey again

Hello kralon20,

Let's make sure Screen Time and Content & Privacy Restrictions are being setup correctly by completing the steps below, that are also listed here: Use parental controls on your child's iPhone, iPad, and iPod touch

Set Content & Privacy Restrictions

1. Go to Settings and tap Screen Time.

2. Tap Continue, then choose "This is My [Device]" or "This is My Child's [Device]."

If you're the parent or guardian of your device and want to prevent another family member from changing your settings, tap Use Screen Time Passcode to create a passcode, then re-enter the passcode to confirm. In iOS 13.4 and later, after you confirm your passcode you'll be asked to enter your Apple ID and password. This can be used to reset your Screen Time passcode if you forget it. 

If you're setting up Screen Time on your child's device, follow the prompts until you get to Parent Passcode and enter a passcode. Re-enter the passcode to confirm. In iOS 13.4 and later, after you confirm your passcode you'll be asked to enter your Apple ID and password. This can be used to reset your Screen Time passcode if you forget it. 

3. Tap Content & Privacy Restrictions. If asked, enter your passcode, then turn on Content & Privacy.

Make sure to choose a passcode that's different from the passcode that you use to unlock your device. To change or turn off the passcode on your child's device, tap Settings > Screen Time > [your child's name]. Then tap Change Screen Time Passcode or Turn Off Screen Time Passcode, and authenticate the change with Face ID, Touch ID, or your device passcode.

Best regards
