I am working on MB1 lesson 9 now. In the previous lesson (8) and in this lesson so far, the png. files to "check your work" after each activity are not working. In all previous lessons (1-7) I could check my work.
Is anyone else experiencing this issue? Maybe it is a bug with the training material.
Does anyone have an idea how I can solve this? Not comfortable to continue plowing forward without actually checking my work along the way.
