I am experiencing a problem while trying to watch an iOS development course in iTunes on macOS. You can find the course here:
https://itunes.apple.com/ru/course/developing-ios-10-apps-with-swift/id1198467120?l=en
If I try to click the play button and watch videos 1 to 6, iTunes just does nothing. It seems to ignore my action. If I try to download the videos, it looks like they are downloading, but they turn out to have formatting problems.
Here is a screenshot:
If I try to open this video I get this message:
The movie could not be opened.
An invalid public movie atom was found in the movie.
or this:
The movie could not be opened.
The file is not a movie file.
But interestingly, if I try watch online or download video from the 6th one to the last one they work properly. I can watch them as well as download them.
What is the issue here? What am I doing wrong?
If I skip something feel free to ask
