Not necessarily. There were many reasons why novels that had been signed but not published included, but were not limited to: 1. The style and genre of the work are not suitable for this platform. For example, some types of works had fewer audiences on the platform, or the author's style did not match the taste of the readers on the platform, resulting in the works not being able to be put on the shelves. 2. Platform editor review failed. The work may contain inappropriate content, grammar errors, or other problems. The platform editor may not approve it. 3. The editing and publishing process of the work has not been completed. The work might need to go through multiple processes such as editing and review before it could be published. 4. Other unexpected factors such as platform updates and maintenance. Writing a good novel was one of the most important factors for a successful creation, but it did not determine whether a novel would be published or not. If you have confidence in your work, you can actively communicate with the platform to try to improve the quality of your work and strive for a chance to be published.
