I've been using the Xfinity text messaging feature on my home computer. The problem is that every few days when I go to check text messages aor send one, I'm asked to sign up for the service. Problem is I've already signed up for it 3 times now. After I hit Signup, I accept the user agreement and then it's "loading" (for up to an hour or more.) Then eventually the text messages I'[ve sent and recieved reappear.
It's not a cache or cookies issue. I can log in and stay logged in one any other website, log in and log out at will. Including the Xfinity website. It remembers my login info just fine. However I have to re-sign up for text messaging. Not every time but enough for it to be very annoying.
