Have to log in EVERY TIME

After getting the new Xfinity infamous three dots on the screen (which I truly believe is Xfinity wanting television watchers to spend more money on a tv box), I deleted the app, reloaded, signed in and now... I have to sign in EVERY SINGLE TIME.  Why? How can I fix this? I have a compatible tv (LG) have been using it all along, everything was fine until Sunday.  

I asked in Reddit and was told to mirror my phone to my tv to watch it that way.  No, I don't want to watch it that way. I pay for a service and want to be able to use it just like any normal app. I don't have to do this with all the other ones, why this? Why now?
