stuck with udemy: bug or site support request?

[therom123]

• I've verified and I assure that I'm running youtube-dl 2018.12.09
• At least skimmed through the README, most notably the FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones
• Checked that provided video/audio/playlist URLs (if any) are alive and playable in a browser

What is the purpose of your issue?

• Bug report (encountered problems with youtube-dl)
• Site support request (request for adding support for a new site)

I was used to download courses from Udemy, now it only downloads one video

• Playlist: https://www.udemy.com/deep-dive-the-openstack-cloud/learn/v4/t/lecture/7748408
  It downloads only the first video in the playlist, but not all remaining videos:
