XFINITY TV app not working - XFinity

I'm trying to switch to the Xfinity TV app, from the TV GO app (which used to work). When I try to sign in to the TV app, I get the following message:

"We are having trouble adding this device to your account. Please give us a call at 1-800-XFINITY and mention error 3329.11005."

I called, and the rep had no idea what the error code was or how to fix the problem. Can someone help?
