While we are checking the situation, please try to remove Snippet Repellent if it is placed in the Storybook Vale, even if it is far away from the place where you are right now. Also, the issue can be bypassed by removing all Snippet Traps from the Storybook Vale. Then the Demon Snippets will spawn in Mythopia, allowing you to progress further.
After progressing through the "A Storm of Stories" quest in the new Storybook Vale update—specifically after following Hades and speaking with him about the whirlwind—the next objective (Catch Shadowy Demon Snippets) appears. However, no Shadowy Snippets are showing up in the Valley.
