For @MattJones and @AndrewJoseph: when viewing the videos from this link (on my device) there are no introductory ads. For a time, those ads were off when viewing on the FireStick app. Now I have seen the same ad (for Indigo Sky Casino) at least 10 to 15 times, the very same ad over and over and over.
Yet if I go to the YouTube app, navigate to WHS, and select the same video, there are no ads. Can you not kill the ads on the FireStick app? I like the Firestick app because it allows all unplayed videos to play one after the other without any intervention.
