If you cannot find the specific audiobook project you are working on right away, it may be hidden because the dashboard only displays a limited number of recent files by default. You can easily access your full history by expanding the list. Follow the steps below to find your project.
Navigate to the My Projects tab on the left sidebar menu.
Scroll down the page past the 'Text to Speech Projects' section until you reach the Audiobook Projects section.
Click the Load more projects button at the bottom of the list to reveal older audiobooks.
