Hi All,

H5P, and any other service that uses YouTube videos, uses the embed version of youtube videos in order to be able to display them outside of Unfortunately, since the embed url that YouTube provides does not work on Safari, you have to contact YouTube support in order to figure out why, there is nothing we can do on our side currently, since the problem is the embed video we're receiving from YouTube and it is their error message that you're seeing.
