We have H5P installed in our Moodle Test instance. However, we did encounter an issue while trying to embed Quiz(Question Set) into Moodle page and Labels. We have created the content using the Quiz Question set, after creating I have embedded it in the label . After clicking on "Start" quiz the page doesn't move forward. This is the same when I embed using "Page" activity.
I have tested this with other components and it works fine for example: I have embedded Memory game into the label.
