Kodi Video add-ons: YouTube Trailers no longer working
Have the Kodie Video add-on scrapper: The Movie Database Python Version 2.2.0

Have the setting enabled for: "Enable Trailer (YouTube)" and it was working great until a few days ago when it opened the YouTube trailer but instead of playing it, we now get the message:

"! The following content is not available on this app. Watch this content on the latest version of YouTube"

My guess is that something changed on YouTube and needs to be changed on the Addon as well.
Therefore, better contact the Addon developers on the Kodi forum.
In this case, Team Kodi.

Sorry, I thought it was created here....thank you for the information, they have information on an updated beat add-on that resolved this for me.
