That is the one thing that irritates me about the Fire TV. Doctor Who sometimes refuses to play saying unable to play and to contact customer service. The only way to fix it is too force stop, clear the data and cache then reboot. Very annoying but what do you expect when you get a butchered old version of Android Jellybean running under Amazon front-end.
