The admin user, as well as the teacher editor, can access the hidden courses in the web version. However, it is not possible to do it in Moodle Mobile.
Would it be possible to resolve this difference between platforms?
I correct my previous message: The teacher can access from the main page (courses), it is correct. It seems that the problem has the administrator, when trying to enter from the list of courses (Site home> Course categories).
I attach a video (sound of the voice in Spanish)
