Bug in the mobile course view
There’s a bug in the mobile course view. After opening a lesson and expanding the table of contents, there’s no way to collapse it.
Mat Kyc Fixed in dev. Thanks for reporting!
Raiyan Marzan also pay attention to the greyed-out / locked lessons when the course is open to everyone.
It’s a bit confusing because the lock icon suggests that access is restricted, but the lesson/quiz can still be opened and completed. Only when submitting the quiz for review does a message appear saying that the user needs to be logged in.
The message should be displayed earlier, with logged-out users prevented from accessing the course, or the lesson/quiz should not be greyed out and shown with a locked padlock icon.
