"All"Cast?

Tried to cast a photo. Selected it, then it searched for devices and found my XBox One, I selected it, the box somehow started the media player, then it showed a black screen for some second and went back to dashboard. Nothing else happened. No error message of Allcast, no photo on the screen. Did not work at all. Who is to blame? The XBox or Allcast?
