We have started making use of H5P and students often access courses using the mobile app. One of the content types we have used is the H5P Interactive Book. It seems that when students get to the summary and submit page, the submit button is not there and so students cannot submit their attempt for staff to view. We have been through all the settings on H5P and they all seem to be okay and there does not seem to be a setting on the mobile app for admin's to change or reconfigure. Please could you advise what we might need to do to ensure that the submit button appears for students.
