Xfinity Stream - accessing current account

I set up for a pending move and set up an account for the new address that just has internet. My plan at my current address uses Xfinity Stream to access our TV lineup and recording through a FireStick. When we login for Xfinity Stream we have no TV or recordings (though we do if I login through the computer browser...website streaming doesn't work with the FireStick browser Silk) and I cant switch accounts, only log out and back in. How can I access the TV stuff at my current address?
