This is a 1 step forward, 2 steps back thing for me.
I like the update to the main app, however, they changed it so your Up Next list of items doesn't show up any more on the main AppleTV dashboard when you hover over the app. now it just shows a big Apple logo where before it'd show a selectable list of episodes. They now want you to go into the app to find this list.
I jump among youtube and my main shows a lot, so I'm never going to spend all of my time in the main app. I'm jumping around the dashboard a lot. Just dumb they took already existing features out to force you to open the app up.
