The Stream video interactivity feature that allows you to embed a quiz or form into the time line of a video does not always work or is very intermittent at best.
Our students we have a video hosted on streams that they're to watch, only about 5% of our students actually had the quiz pop up while watching the video with the rest having it pop up with 'loading' and then disappearing or not having anything show up at all, despite having the time stamp indicators on the time line as to when the quizzes are scheduled to show up.
Even for myself as admin when I watch the videos in streams, regardless of where I am or the internet connection, sometimes the quiz will pop up, most of the time it won't.
@stedmana Sorry to hear that you are seeing issues with Interactive Forms. Would you be able to share a "session ID" (? -> About Microsoft Stream -> "Client Session ID") from the session where you are seeing this issue, so we can investigate further? Also, what OS and browser version are you/your students using?
