I called comcast to ask them if xfinity stream app would work with fire tv stick. the rep even put my call on hold for a few mins, then came back on the line and said yes. Well comcast is getting another call today, now they will credit my accout for the total cost of the firestick, since the rep assured me it can get the app. the only reason of my purchasing this fire stick was so I can yank out those set top tv boxes which at one time they gave out 2 and each additional was only like $0.99. .
