I'm not using a live wallpaper, just an ordinary image I downloaded off Google. The option is just not there, only the lock screen option is. It was working fine before I installed a 'live gif wallpaper' app but I uninstalled the app because I just wanted a normal wallpaper and now it's not working.
Phone is a Galaxy Samsung A71.
Maybe you can try setting a free theme to see if that gives you back control over changing your wallpaper. You could also see if samsung theme park app would be an option to apply the wallpaper. You can download it from the galaxy store it is also part of goodlock.
