Hello @scoprio !
We checked at our end on our testing websites and the options seem to be working.
It looks like there might be some conflict on your website with any other third-party plugin or theme.
To debug the issue, I would request you to please try deactivating all the plugins you have one by one and try switching the theme temporarily to the default WordPress theme like Twenty-Twenty One, Twenty-Twenty to see if Snow Effect starts working on the frontend or not.
Also, it would be helpful if you can share the link to your website here so that we can also check if there is any issue or error on the front end.
