Apple TV app not staying logged in across devices

I use the AppleTV app and I have to login to the app everyday. It did do that before and has been happening for about a month. I use it in my room on a DirecTV Gemini stick and in the living room on a Chromecast. Each one asks me to login everyday and it is annoying. Anyone know what changed and how to change it back?
