apple tv constantly asking for sign in

We live with the Xfinity Stream app on Apple TV because when it works correctly, it is a far better experience than anything. It has glitches. Two huge ones, that are maddening, especially for an app that has been released for a while and has had literally NO updates to fix the problems. (1) the last item in the guide, the bottom of the list will jump to some crazy place when you click it. One must scroll down again and get lucky just to make it work. It takes much clicking and cussing. This is frustrating. (2) the app asks for sign in quite often. At least 3-4 times a week and even 3 or 4 times in one day. Geeeeeeze. Find out what is the problem and fix it. I would love to recommend the app to my friends, but they will constantly call ME for help when they encounter issues. Luckily I can use the phone to enter the sign in details using saved logins, but it's ridiculous to go through the motions and have to do this.

Maybe it helps to tell you when I noticed this happening repeatedly. We listen to Pandora music on Apple TV almost all day. When switching over to Xfinity Stream, it requires the login. Almost every time. Maybe that's a clue. Please fix this. I love the Apple TV experience, but patience is wearing thin.
