Mesmo problema! Antes essa informação era enviada e de repente parou de funcionar.
Yago,
By default the video runs on a Tutor player, to solve the problem while they analyze it, I put the videos to run on the Vimeo player.
Go to Tutor> Settings> Course … in “Preferred Video Source” check “Vimeo” and “Default Video Source” check “Vimeo”.
Here it works again.
Until they manage to solve the problem, I think it is a valid solution.
