The "Autoplay next story" feature during "Night Mode" only applies to albums in the "Create your own stories" category.
If you choose an album that does not appear in the "Create your own stories" category, the volume and brightness of My Fabulous Storyteller will decrease but there will not be a continuous flow of stories within the album.
Thanks to the "Night Mode", the visual and audio revival between each story does not take place, the stories of the album are linked without asking to create a new story, to encourage your child to fall asleep 🌙. As a reminder, it is possible to choose the number of stories before the device goes to sleep in the customization of the "Night Mode" settings (see how to customize my "Night Mode").
