I chatted with Netflix about this:
Netflix Angel
Thanks for contacting Netflix. My Name is Angel, how can I help you
today?
You
Hey. I want to give you feedback on the new Apple TV app.
You
Where do I do that?
Netflix Angel
Hey, you're reaching out to the correct person, I will make sure to forward your feedback through the proper channels.
You
Ok. I really hate that the app won't me finish a movie. There is no way to see the end credits in full screen.
You
I have tried to turn of auto play next episodes under settings, but the app still minimizes the playing video at the end.
You
Hate is a strong word, I really dislike.

Thank you for this feedback, and I really appreciate you taking your time to chat with me, you're correct, the Credit screen does minimize on the new UI for the Apple TV, I will make sure to submit this through the proper channels, so we can add an option to turn it off and add the movie suggestions until the end credits or if you decide to skip the credits
You
Thanks!
You
It ruins some films completely.
Netflix Angel
My pleasure, I know where you're coming from, some Films really have some added value from the credits.
You
Bye.
Netflix Angel
In the meantime, you can restore the Credits to full screen by selecting the minimized screen and clicking on it.
You
Nope.
You
Not on the new Apple TV. =(
Netflix Angel
:C
You
I tried that.
Netflix Angel
What?!
You
I can only rate a film.
Netflix Angel
Then I really thank you for taking your time with the feedback, I'll add this notation before I submit it.
