The new videos have almost no subtitles. For example the MS-900 course and some new videos of the AZ-104 course
The support rightly confirms that new publishing courses take time, but for the AZ-104 course it says it is in production.
Actually the course is released, some are the old videos (and all have subtitles) others are the new courses that were put up as an update and don't have the subtitles. The dashboard talks about an AZ-104 in production but I don't think it's related to these videos already published.
Is it possible to add the missing subtitles? For those who are not native English speakers it is essential to have English subtitles to better understand the lesson.
