My roku stick was working fine with the app at my family's home under their comcast id and password. When I brought it home it keeps getting an error after entering the authorization code. I am able to run the app on my mobile and laptop at home. I have xfinity tv and internet with my own router. Any advice would be greatly appreciated.
I'm confused about the locations. Did you move the Roku to another network? The app will only work if the TV and Internet account are the same and it's connected to that home account. You cannot use the Roku app if you do not have your own TV service, even if you do have Comcast Internet service.
