If an app or feature on your device is not working, not appearing, or is restricted (grayed out), it may have been disabled using Screen Time, or by an IT administrator if you are using a device owned by an employer or educational institution.

Tap Settings > Screen Time > Content & Privacy > scroll to Allow Changes.
- If the device is managed (Settings > General > VPN & Device Management), contact the IT department that is doing the managing.
If an app is not appearing, see: Use parental controls on your child's iPhone, iPad, and iPod touch - Apple Support "If you turn off an app or feature, the app or feature won't be deleted, it's just temporarily hidden from your Home Screen."
If you are using Family Sharing, make sure this isn't a Sharing related issue such as happened in this case: Change Payment Method - Apple Community
E.g., If you are part of a family group but not the Organizer, you cannot add your own payment method.
If you see a message saying to try again later, see if it's a system issue: Apple - Support - System Status
Here's a list of standard things to try when a feature is not working:
Make sure the software is up to date on all devices involved.
Update macOS on Mac - Apple Support
Update your iPhone or iPad - Apple Support
Sometimes it helps to have the devices involved take a fresh look at settings:
● If this is a service, try disabling it and turning it back on.
● Try signing out of accounts and back in again.
Sign out of iCloud on your iPhone, iPad, Apple TV, or Mac - Apple Support
Sign in with your Apple ID - Apple Support
If you have more than one Apple ID, don't forget you may be signed into other accounts too for special services such as iMessage and Media & Purchases.
● Restarting is a simple step that can resolve many unexpected behaviors.

Try using other equipment if possible. I have seen several cases where somebody tried to do something on one item of equipment and failed, but then tried on a different item of equipment and succeeded.
Sometimes it can take some time for changes to propagate through the system and waiting may help ( e.g., https://discussions.apple.com/thread/254632281?answerId=258650468022#258650468022 ). If a problem persists, particularly over several days, try contacting Apple for assistance:
