Wallpaper theme won't work on lock screen

[Android Central Question]

I have a note 9, and up until a few days ago my lock screen/ wallpaper theme worked fine. I downloaded the theme from the Samsung themes a couple weeks ago and it worked fine.
But a couple days ago something happened, and now my wallpaper on the lock screen reverted back to one of the standard Samsung wallpapers. I have tried everything, including changing the theme and I can't get the theme to work no the lock screen any longer.

Try Wallpaper Wizardrii. I don't know if it will work or not, but it's free, so try it. (It's worked for me in the past.)
