Hello, since my Galaxy S10+ was updated with the new One UI 3.0 with Android 11 a few days ago, a very annoying bug is automatically changing my lock screen wallpaper. I use one of Google's live wallpapers for both lock screen and home screen, but at some point during the day (usually at night or when the phone is charging) the lock screen changes to a rotating display of wallpapers. Seems like the problem is related to the Dynamic Lock screen option under "Wallpaper services", even though I have this option set to None it looks like its changing my wallpaper nonetheless.
Same Issue for me. I have a note 9 and it is very annoying.
