"Teacher view is not available for this puzzle" - in Minecraft Adventurer and others

I am able to display the progress of my students, and I can even spot puzzles solved in a sub-optimal way (“too many blocks”) as pale green dots. However when I’m trying to see WHAT is the problem with the student’s code, after clicking the green dot all I see is the message “Teacher view is not available for this puzzle”. Is it possible to enable it somehow, or the Minecraft puzzles simply doesn’t provide this feature?

I have the same problem. Help me please!!! Thanks.
