Netflix doesn't have ads you have to sit through which is another reason why they are killing the streaming game right now. But if you have watched recently, you may notice that although they know are giving you 12 seconds before auto playing your next episode, they are shoving clips of their original shows any chance they get.
THERE IS A WAY TO OPT OUT....and here it is.
1. Log into your Netflix on your computer...yes, this is old school but only takes a few seconds. Go to your profile avatar, hover over it til you see the drop down menu and hit "account"
2. In Settings click on "Test Participation"
3. Switch it to "OFF" and grab a cold beverage you are officially productive right now.
