The Home Screen's recommendations row is kind of pointless. If I have Hulu installed, it will list popular shows on Hulu. I have no interest in any of these shows... so I end up just hiding the Hulu app from the recommendations. The same goes on for Twitch, YouTube, HBO, Showtime, etc... So basically I've disabled everything because of how pointless it is.
Is there a way to change the recommendations row so it instead shows updates to my subscriptions?
For instance, for Hulu, when one of my subscribed shows has a new episode... it should show that. With Twitch, when one of my followed channels is live, it should show that. For YouTube, new videos in my subscriptions, etc...
No. It's all dependent on how the app developer designates it.
Even Google's implemention sucks; it pulls from trending videos instead of videos from your subscriptions.
This will all change with Oreo though.
