I will say that the 10.11 update for me was a freaking nightmare with so different types of failures.

I'm still waiting the ability to remove seasons without deleting the media, especially since I now have ton's of duplicate season_xxxx seasons from the major version update, mucking up most of my seasons that I didn't have before.

Oh and chromecasting on the app is still a giant mess.

Still great to hear they're making progress.
