Advertisements Thanks for the correction. I now recall that I had originally installed Showtime Anytime on the Shield and then deleted it when I discovered that I could not use it with my Comcast sub. And I was not aware of the iOS and Android mobile permissions; I will bear that info in mind for future reference. However, it's not true that Comcast will not support authentication of any third-party SVOP apps on Android TV. In fact, I used HBO Go on the Shield with my Comcast HBO sub for several years (unless my faltering memory is playing tricks on me again) until I signed up for HBO Max via WarnerMedia in May. But SHO and Starz were a no-go. I'm currently getting SHO for free as a "customer courtesy" so I will stick with Comcast for now.
