Has anybody else experienced this ?

In the YouTube app that's pre-installed on the Chromecast (the one with Google/AndroidTV included), a video will sometimes prematurely end.

I'll be logged into my Google account through the main interface. I open the YouTube app and click on a video. The video will play normally for about 10 seconds before the sound begins to gradually fade out. After the volume has hit 0, the end-screen appears with the countdown for the next auto-play video.

The annoying thing is that this often happens when playing a recommended video and when I hit the back button, I'm presented with new videos.

I've re-started the app and the Chromecast. Any reasons why this might be happening?
