Apple TV apps like Disney on multiple devices.

I subscribed to Disney plus on one of my Apple TV s. Works no problem. When I download the app on another tv, iPad or iPhone, which are all logged in to the same Apple ID account, it wants me to sign up with an email and password. That is the only option given. If I try my Apple email and password it says it is incorrect. I have not had this problem accessing other apps such as Netflix or Prime across my devices.
