Why is one of my app not showing all required features?

Hi odejobi220,

Are you attempting to change the privacy settings for a specific app? If so, check your current restriction settings with the steps below found in the article here: Use parental controls on your child's iPhone, iPad, and iPod touch - Apple Support

"Allow changes to privacy settings

The privacy settings on your device give you control over which apps have access to information stored on your device or the hardware features. For example, you can allow a social-networking app to request access to use the camera, which allows you to take and upload pictures.

To allow changes to privacy settings:

1. Go to Settings and tap Screen Time.
2. Tap Content & Privacy Restrictions. If asked, enter your passcode.
3. Tap Privacy, then choose the settings that you want to restrict."

Best.
