Apple TV Not Playing Disney+ Movies?

Okay, I just got my iPad and it comes with 1 year free subscription to Apple TV. However, today when I tried to play one of the shows I wanted to watch it (1) asked me to install Disney+ app and (2) kept redirecting me to the Disney+ webpage every time I tried to play the episode.

Do I need Disney+ (aka additional subscription for something that seems to be advertised to be part of the Apple TV plan) to watch the featured Disney+ movies/shows?

I have also restarted the app and the device... the issue remains.

Thank you.
