Can't open online material
I'm a teacher and my first try to use Smartphones with GeoGebra in class was almost a failure. Many pupils had no option shown to open online materials, as their menu showed only "new", "share" and "test mode". I tested this only on my smartphone before class, however in class I realized, that my own iPad's menu was also showing these three points only. We solved the problem by using the browser version instead. Bug, feature or UTS (user too stupid) error...?
I attached screenshots from my iPad and my Android phone:
