Xfinity Stream Beta App Problems - XFinity

For the past week I have not been able to use the Xfinity Stream App. I have Un-installed, and reinstalled it. And it presents with a black screen on it and a single white horizontal line across my smart TV screen. I have a newer Samsung Smart TV and this app doesn't work. I have restarted my modem and tested my connection thinking it was the internet, but that didn't seem to help either. Customer service is so hard to get ahold of regarding this app as well.
