I have a positive experience using Chromecast. Mostly, I use it to cast YouTube, and Spotify (sometime). But, recently I use Netflix more.

I did not how it was started, but yesterday I could not cast Netflix on my Chromecast. Nothing was changed. I used the exactly the same setup.

When I tried to cast YouTube, it worked without any issues, but not with Netflix. After few attempts, I finally have it worked again by reinstalling the Netflix app on my Android phone. Everything is back to normal again now.
