Hi Alicia!
MoodleCloud currently has 3.9.2 and the interactive book issue mentioned here was fixed for Moodle 3.9.3 onward. However, we have good news for you: the MoodleCloud team is working for upgrading the Moodle version to 3.10.1 so, in about 2 weeks, all the MoodleCloud sites should be upgraded to this version
Kind regards from Barcelona!
