iReader is an e-book reader. A long novel needs to go through several steps to be imported into iReader. The following are the possible reasons for failing to obtain chapters: 1. The issue of copyright: A novel usually requires the authorization of the copyright owner to be published and published. If you don't have the copyright owner's permission, the chapter will fail to be imported. 2. E-book format problem: In iReader, novels usually need to be converted to a specific format before they can be imported. If the format of the novel does not meet the requirements of iReader, the chapter import will fail. 3. Word count problem: A novel usually has many chapters, and the word count of each chapter may be different. If the word count of some of the imported chapters exceeds the word count limit of the iReader, the chapter import will fail. Version 4 issue: Each e-book version in iReader has its own specific format and restrictions. If the version of the novel does not meet the requirements of iReader, the import of the chapter will fail. 5 Other problems: There are other problems that may cause the chapter import to fail, such as damaged e-books, iReader system errors, etc. If there was a problem with the chapter acquisition failure, you could try to check the format of the e-book, the word limit, whether the version meets the requirements of the iReader, and whether the e-book is complete. If the e-book has any damage or missing parts, you may need to download or repair the e-book again.
