Doesnt Work With Comcast

Heres the problem.
I cant believe Starz wont work with my Comcast/Xfinity Subscription.
I can watch Starz at home, but when Im out forgetaboutit. When I tried to login, Starz had every provider except Comcast/Xfinity.
I have to place the blame on the Starz App, until I hear different.
I Really Dont Like Giving Bad Reviews, but I have no choice here.
If Im contacted by the developer (its happened in the past) I will change my review and place the blame where its due.
Thanks For Reading
