Unable to delete apps on iPhone with parental controls enabled

Re: "Unable to delete apps on iPhone with parental controls enabled : I tried to delete apps multiple times on my iPhone, but even with the agreement on parental controls to “delete apps” it doesn’t work"

See if Apple Support's online article can help:

For iOS 18: Remove or delete apps from iPhone - Apple Support

Eg: says:

"Delete apps

Do any of the following:

• Remove an app from the Home Screen:
• Touch and hold the app on the Home Screen, tap Remove App, then tap
• Remove from Home Screen to keep it in App Library, or tap Delete App to delete it from iPhone.
• Delete an app from App Library and the Home Screen: Touch and hold the app in App Library, tap Delete App, then tap Delete. (See Find your apps in App Library.)

If you change your mind, you can redownload apps you remove."

Re: "It just says that I can either “remove it from Home Screen” or “add to Home Screen”. "

Seems you may just be organizing / moving the app icons when that message happens:

See how to: Move apps and widgets on the iPhone Home Screen - Apple Support

Eg: says: to move apps:

"Touch and hold the Home Screen background until the items begin to jiggle."
