Not a glitch. Webnovel said they are going to be reviewed by some 3rd party soon and put @everyone on their discord saying to temporarily get rid of all mature covers and tags. If you have any the will make it where no one can see your story (unless it is in our library) and you cant get power stones. I am not sure when they will bring it back. If I remember right it should be in 2-3 days.
Yeah, almost all my books disappeared too. I talked to the service person and they said that the editors are going over the novels for some Apple Store Audit. The only thing that happened was the loss of power stones and the books are concealed by Webnovel, they said it would take at most a week. I don't know what happens if they have problems though.
