Hi, sorry, I didn’t get a notification about this post.
I just looked into this and it the scroll snap seems to break scrolling effects even without my plugin. Elementor has it’s own built-in scrolling effects system. You can see it here

I tested using this method without my plugin installed and switching scroll snap on and off was breaking the feature. Looks like they even broke their own stuff with the new feature, unfortunately.
This seems to just be a bug with scroll snap, hence it still being an experiment. They will most likely fix this soon, I hope they do anyway. Sorry you are having problems but it looks like it’s on their end.
Edit: I saw that other were having the same problems in their support forums. I’ll also be reporting this on their githug. Thanks again for bringing this to my attention and sorry for the trouble.
