Can’t change wallpaper on ipad
for some reason I cannot change the wallpaper on my iPad since update to ios18
iPad Pro, iPadOS 18
The methods by which Wallpaper images are managed has changed lightly in iOS/iPadOS 18.x - as Wallpaper can be managed from iPad settings and directly from the Lock Screen.
The iPad User Guide may provide the guidance that you need:
Change the wallpaper on iPad - Apple Support
Create a custom iPad Lock Screen - Apple Support
If you are still having difficulties, please describe exactly how and where the process is failing.
