In 26.60, you can't edit writable_books anymore once the number of entries reaches the limit.

With the 26.60 update, the number of characters you can write to writable_book Japanese has been reduced.

With this update, the width of NotoSans's characters has been unified with the Java version, but with this update, if the text is visible beyond the display limit on a single page, you can no longer add, delete, or break lines on that page.
