I can't delete apps from my app library anymore

iOS built-in apps cannot be deleted, but they can be removed from the home screen in recent versions of iOS. Removing the app from the home screen doesn’t delete it from the device; it simply hides it.

Photos, Camera, Clock, App Store, Wallet, Safari, Phone, Message & Find My apps.

First disable the Screen Time Restrictions, if any.

Settings > Screen Time > Contenet And Privacy Restrictions > iTunes & App Store Purchases > Deleting Apps > [Allow]

There are six possibilities

1. Delete an offloaded App
2. Delete an App from the Home Screen
3. Remove an App from the Home Screen - Will be placed in the App Library
4. Delete an App from the App Library
5. Delete an inbuilt App - Not feasible
6. Delete an inbuilt App with one feature - You do not get any options either (e.g. Magnifier)

Try this:

1. Open Settings
2. Tap Screen Time
3. Tap Content & Privacy Restrictions
4. Tap iTunes & App Store Purchases
5. Make sure Deleting Apps is marked Allow

Turn them on and then check.

Are you a member in a Family Sharing group? In that case, it makes no difference what settings you have on your device, the limitation is set by the Organizer.

Thank you very much

Do you have any Profiles installed at Settings > General > Device Management?
