I am trying to stream a movie purchased through iTunes on an iPad without the data connection through tethering through my phone's personal hotspot and it is saying I need to be connected to wifi. I can't figure out why apple would not let you use your cell data if you want to. I can stream all the Netflix, HBO, Hulu, etc. I want through this method but not the movies I spent money on through apple? Is there a way I can do this I am not figuring out?
