Just for the interest of other users. If you turn on the feature ‘Hide playbar in Quiz’ to be found under Quiz Preferences, Settings, the playbar is automatically hidden on the score slide as well. This is a recommended setting for quizzes to avoid having learners being blocked on a quiz slide when navigating back. For the same reason it is also recommended to hide the Back button (without preventing Backwards navigation). One exception for these recommendations: when Submit All is chosen.
