Rise - The media could not be loaded, either because the server or network failed or the format is not supported

Hi Daniel!

We'd love to have a closer look at your file to try and nail down why this is happening. If you don't mind sharing it, you can send it our way by clicking here.

In the meantime, we've heard that some course authors have resolved the issue by duplicating the lesson with the video, deleting the original lesson, then re-publishing the course for LMS.
